king · Answer

why?according to ure previous reply u hav already solved it or r u solving it nw?

anonymous · Answer

ok....everything is fine..now my ans is quaranteed!

anonymous · Answer

John's age = x years
Sister's age = x-24 years
brother's age = x+16 years

As per the question, sum of the ages = 100 years..

=> x + (x-24) + (x+16) = 100
=> x+x-24+x+16 = 100
=> 3x -24 + 16 = 100 .. 

Since, you just want to know the answer,

John = 36 years..
Sister = 12 years..
Brother = 52 years .. 

Do our answers match ?
