Could you post the question please?

When it explodes,momentum is conserved,so its neither a nor b.

Further,kinetic energy will also be constant.

So I think its e.

2)Let sales of week2 be=x

Allowing 10%increase,

sales of week3=x+x/10=11x/10

similarly,

sales of week 4=121x/100

From question,121x/100-11x/10=115.50...

solving,x=Rs.550

Thats it!

Hey Nishant-small error there:

In the question it already says that 5 appears on one die.AFTER this,we have to calculate the probability,which will be 2/6=1/3.

On the other hand, if the question was "A pair of dice is thrown.What is the probability of getting a sum greater than ten  AND five on one die?",then your solution is perfect..

Cheers!!

Buddy you can use fav.outcomes/tot. outcomes only when each event is equally likely to occur,right?Here I dont think thats the case..

 

 

yup...I think thats the only way to do it,right?

all the correct solns i saw were using that itself..

thanks!!

Thanks all !!

Btw polymath,will you give second derivative too?

Thanks

Thanks buddy...I was on the right path after all...

Thanks again

lol!!!

another weird idea i had...thanks spidey & polymath!!

Its pretty clear now!!

Find dy/dx,

where y=a(1-cos)

        x=a(-sin)

Kindly give solution also.

Rates assured
