A asks how old are they?B decides to plot a riddle to test A of his mathematical capabilities.B says the product of their ages is 36 and sum of their ages is equal to my house number,which he tells to A.A carefully notes down B's house number& then takes a moment to think, and replies that the data is insufficient. At this B provides anothr data that- my eldest daughter has blue eyes. After hearing this A immidiately replies B with correct answer.

since the product 36 can be split as 1x2x2x3x3 hence the possibilities are 2,3,6 /2,9,2/ 3,4,3/12,3,1
since b mentions that his eldest daughter has blue eyes and a immediately replies hence a has seen his eldest daughter perhaps 10 yrs ago hence answer is 12,3,1

1,4,9. OR 1,1 36, OR 2,2,9 ... etc.

the trick i saw was that the ans could have been 6,6,1. but since the ELDEST daughter has blue eyes, obvoiusly this ans is wrong, because there r 2 eldest here..

of the above 3, only ONE will add correctly to the house number.
GREAT SUM!!!!

HELLO, the question asked wasn't too tuf but the main thing was to understand and read it properly. i think the correct answer must be 6,2,3 if u take it to be a simple case! but yes answer can be 433 or 922 etc. if 2 daughters r born on the same day! and one dude answered 36,1,1 DON'T U FEEL ITS A RARE POSSIBILITY!!!!!!!!!!!!!!!.Well while cracking this problem keep the word 'eldest' in mind and start making the factors of no.36

all wrong. da ans is 9,2,2.


here's how:


put down all cases of product being 36. now, da person knows da sum is da house no. so da 1 wid da given sum wud b da ans. but as he wants another clue da data is insufficient so da options wid da same sum are 1,6,6 and 9,2,2. in da third clue she says tht da eldest has blue eyes. in only 1 case is there an 'eldest'.


plz rate.

since he mentioned as eldest daughter(only one)  and they met after 10 years , their ages may be


9,4,1


9,2,2


6,3,2


when we see in scientific way  2 childern willnot born in consecutive years so the options are


9,4,1


9,2,2


since twins are rare it may be  9,4,1


 


if answer is correct please vote for me
