This is called BUSINESS.  ( Kaun Banega Crorepati )
6 * 100 * 10 * 20 * 20 = 2400000
24 lakhs in 20minutes..
cue is KBC 2!
Any guesses ??
6(Rs/SMS) * 100(entries) * 10 ( cities ) * 20 (districts ) * 20(states ) = 6 * 400000(people trying for the 2 lakhs cash price )
Imagine what if 1000 entries try out from 100 cities ??
The figure simply grows by 2 more zeores and yields a whooping 24Crores!!
And it does not stops there... 1000 entries from 100 towns is a very small
number ..in practice it could be another multiple of 100 or worst case a
multiple of 1000 on an average..
In that case it is 24 * 100 crores earnings in just 20 minutes on every
episode!
And the price money :-)) mere 2 CRORE ( and from whose pocket? )
Smart Buisness by SidharthBasu  & Star!
This calculation is just the SMS earning!
What about the Ad money ??
A rough annual profit calculation goes like this ..
2400 * (5 * 4)(episodes/month) * 12 = 576000 crores
Let even 50% get expended in taxes and other payments, still you will be
left with ( which includes even the meagre 480 crores of price money..i.e.,
if every episode bags 2 crore prize!! )
2,88,000Crores profit ( only from SMS !!!! )
Community shelf Community shelf -> RUN RATE Calculation -> Go to message
This Post 4 points    (Olaaa!! Perrrfect answer.   in 2 votes )   [?]

The net run rate for any team is simply the rate at which it is scoring runs minus the rate at which it is conceding them. It is, therefore, the total runs it has scored divided by the total number of overs it has played minus the total number of runs it has conceded divided by the total number of overs it has bowled.

Example: If Team A scores 250 runs in 50 overs, its run rate per over is 250 divided by 50, that is 5. If Team B scores 200 runs, its run rate is 4. Hence, Team A?s net run rate is 5 minus 4, that is, 1.

There is a caveat. In calculating run rates -- whether the scoring rate or the conceding rate -- a team that has been bowled out without batting through the 50 overs is treated as if it has played its full quota of overs. Thus, for instance, when Bermuda was bowled out by Sri Lanka for 78 in 24.4 overs, its scoring rate would be calculated not as 78 divided by 24.4 but as 78 divided by 50. Similarly, Sri Lanka?s conceding rate would also be 78 divided by 50.

Does batting first or second matter?

For any one match it does not. A team that scores, say 450 and bowls out the opposition for 50 would have an NRR of 8 for the match. So also would a team that bowled first, conceded 100 and then chased the total in 10 overs. However, when its NRR for all the matches is taken into account, the former result would be more beneficial. To understand why, consider this:

-- Suppose team A has already played one match in which it scored 250 in 50 overs and then bowled out the opposition for 200. Now, in its next match if its scores 450 and bowls out the opposition for 50, its NRR at this stage would be 450 plus 250 (i.e 700) divided by 100 -- which is 7 -- minus 50 plus 200 (i.e 250) divided by 100 -- which is 2.5 -- working out to +4.5.

If instead, it had in the second match bowled first, conceded 100 and scored 101 in 10 overs, its NRR (by a similar calculation) would be just +2.85.

Thus, despite the NRRs for individual matches being the same in both scenarios, the total NRR is quite different. This happens because the calculations ensure that high-scoring matches carry greater weight than low scoring ones.

ONE PARAGRAPH THAT EXPLAINS LIFE!
Arthur Ashe, the legendary Wimbledon player was dying of AIDS which he got due to infected blood he received during a heart surgery in 1983. From world over, he received letters from his fans, one of which  conveyed: "Why does GOD have to select you for such a bad disease"?
To this Arthur Ashe replied: The world over -- 5 crore children start playing tennis, 50 lakh learn to play tennis, 5 lakh learn professional tennis, 50,000 come to the circuit, 5000 reach the grand slam, 50 reach Wimbledon, 4 to semi final, 2 to the finals, When I was holding a cup I never asked GOD "Why me?".
And today in pain I should not be asking GOD "Why me?"
Happiness keeps u Sweet, Trials keep u Strong, Sorrow keeps u Human, Failure Keeps u Humble, Success keeps u Glowing, But only God Keeps u Going.....

Community shelf Community shelf -> Simple multiplication by 11 -> Go to message
This Post 5 points    (Olaaa!! Perrrfect answer.   in 1 votes )   [?]
Take an example:Large number 
 
Multiply 3589547856996 X 11
 
General Procedure is to multiply it first by one and then again by one and
at the end do the addition to end with the results.
 
Here we do the same thing,except multiplication we are going to do additions.
Let us see how.
 
Write the unit digit as it is.ie. 6 in our case.
Now add 6+9 which equals to 15,take down 5 in tens place and carry 1
to next number i.e.9.
Now add 9 of tens place with 9 of Hundreds place which equals to 18
add 1(carry) + 18 which equals to 19.write down 9 at hundreds place and carry forward 1 to next number i.e.6.
Do the same procedure till the end of the digits and then take down 3(the last digit) to our total to end with result.Try this with calculator and will get the same answer.
 
Take an example of small number 53 X 11
 
write down 3,Add 5+3 which equals to 8 and then take down 5,and you will end
up with answer 583.
 
Give me your feedback if it does'nt make sense.

****** DeviceNet De-mystified... The Basics ===================================================
DeviceNet has been around for just over a decade. It extends back to a time I like to refer to as 'the war days'... that is the bus war days.
In the early-mid 1990's most PLC manufacturers were trying to develop the 'standard bus'. Naturally this can only lead to one thing for the industry. (ie. a mess and no real standard) Well, guess what we got folks?? That's right, a mess and no real standard. But I'm sure no vendor would say that 'on the record' because their bus IS the standard... as long as you're using their PLC that is.
DeviceNet is one of the many 'fieldbuses' available on the market today. Fieldbus is a big techno-word that basically means a network that is optimized to exchange data between small devices and a main larger device(s). The devices send/receive status and command messages to each other. It's main purpose is wire saving. We'll explain more details later on... and see why wire savings is a HUGE benefit.
The early days of DeviceNet were the Allen-Bradley only days. But in
1992 they started to share information with the automation community and even invited competitors to become members of their DeviceNet community. At the March 1994 ICEE show in Chicago DeviceNet was released to the automation world and in 1995 Allen-Bradley 'surrendered' DeviceNet to the ODVA (ie. Open Device Vendors
Association) It remains an open protocol today and anyone can get the actual specifications... for a $300 fee that is.
DeviceNet is quite smartly based on CAN (ie. Controller Area Network).
Honeywell also has a bus called SDS that is based on CAN as well. (See what I mean about bus wars... everyone has a 'standard bus'. I'm going to call my bus 'school bus'... ohhhh- that's already taken) CAN comes from the automotive industry and was developed by BOSCH in Germany for Mercedes way back in the 1980's. Back then Mercedes and all cars had a 'wiring harness'. (lift the hood of an older car to see the spaghetti wiring of the time...) The wiring harness was essentially the control panel for the car. All of the cars wires went back to here and it was obviously 'chock full' of wires. There had to be a better way of sending all the wires back to here. So, BOSCH engineers developed the 'CAN bus'. Now a single cable could be wired throughout the vehicle and the individual systems (ABS, brake lights, locks, windows, air bag, etc) could just 'tap into' it. The bus also distributed power... so hopefully you can easily see the wire savings.
To see this wire savings benefit in our factory environment, let's look at an example:
DeviceNet allows up to 64 'nodes'(ie. taps in the car example above).
That's actually 63 nodes and 1 brain. Each node has a simple device connected to it.(like a sensor, for example) Each sensor will need power (so that's 1 wire for + and 1 wire for - ) and a signal wire so we can know if the sensor output is on/off. So, each node (device) connected needs 3 wires.
The maximum distance we can go to maintain the fastest speed is 100 meters. We can go 500 meters at the slowest speed but let's use the fastest speed for our example.
We therefore need 3 wires x 100 meters x 63 nodes = 300 x 63 = 18,900 meters of wire! Since 1 meter is about 39 inches, we'd need about 737,100 inches or 61,425 feet of cable... WOW. I want to see you troubleshoot a wiring problem in that application! How would you color code the wires??
By using a bus system like DeviceNet we'd dramatically reduce the number of wires needed. A DeviceNet bus has 5 wires bundled together
(2 for power, 2 for communications signal, and 1 shield). We'd run the bundle the full 100 meters and tap into it near each device to connect the device to the bundle. The taps are generally quick-disconnect connectors so wiring is simple. Now to troubleshoot we'd simply make sure the bus was alive (easy if the devices up the line were working) and then check the individual device where the problem was.
Simple. Neat wiring. Easy to follow. Easy to document. Easy to setup.
Easy to troubleshoot.
Since DeviceNet is based on CAN, which comes from the automotive industry, it has a background of high reliability and speed. (If your air bag doesn't work because of a bus fault or delay that would be a problem... wouldn't it??) The DeviceNet brain (ie. cpu) is also good in tough environments (since they are derived from the automotive
industry) so high temperatures and noise are not a major issue.
Devices such as motor starters, variable frequency drives, HMI displays, barcode readers, sensors, and even limit switches are all available with DeviceNet capability built-in.
Let's now take a look at the specifications of DeviceNet real quick and explain each.
DeviceNet is an 8 byte bus system which translates to the fact that it doesn't send as much data as something like Ethernet so it's good for small device communication (like sensors, motor drives, etc) as opposed to computers and other 'data hungry' devices.
The devices all connect to a single DeviceNet cable via taps into this main cable. (Like branches on a tree all connect to the trunk, for example. The leaves would be the individual devices but wouldn't fall off when the weather starts to get cold like here currently in NY
state!)
Everything 'talks' at speeds of 125Kbps (125kilo-bits per second. Kilo means 1000 so 125Kbps is 125,000 bits of data per second), 250Kbps or 500Kbps. On a thick cable at 125Kbps we can have a maximum trunk (like a tree) cable length of 500 meters. (that's a tallllllll treeeeee!) At 250Kbps the cable can only be 250 meters max. And at the fastest speed of 500Kbps we can have a 100 meter max trunk cable length.
Each tap into the main trunk cable (like a branch on the tree) can be a maximum length of 6 meters regardless of the communication speed. (So the branches on the tree can be 6 meters long maximum) The total of all taps can be a maximum length of 156 meters at 125Kbps, 78 meters at 250Kbps, and 39 meters at 500Kbps. (chop all the branches off the tree trunk and lay them in a line end-to-end and their total cumulative length cannot not be longer than 156 meters... assuming slow speed)
We can draw a maximum current of 8 amps through the system (remember that power is supplied to all devices on the trunk line at 24VDC)
There is also duplicate address detection. Each node supplies an address that cannot be duplicated.(otherwise who are we 'talking' to?
Like if there were 2 Phil Melore's standing next to each other how would we know which we were talking to???) When the node is connected to the bus it announces it's address (ie. name) to the network. If the address (name) already exists on the network, that new device will not be allowed to be put into 'run mode'.
There is error checking done by the CRC method. (Cyclical Redundancy
Check) Ethernet uses it and basically makes sure that the data that was sent is received without error. (ie. You say 'hello' and I receive 'hello' and not 'herra')
Each end of the trunk cable needs a 'terminator'. Basically this means that we add some electrical resistance (121 ohms each end of the cable) to each end of the cable to electrically 'balance' the network.
Finally, just for reference, black/white conductors are specified for communications, red/black for power, and a bare braid for shielding.
