Question

Present age of a is 11 years more than present age of

b. after 5 years, age of a will be 4 times of what b was 2 years ago. find present age of

a.

Answer 1

let the present age of B be x.

then present age of a will be 11+x
After 5 yrs, age will be
a=5+11+x=x+16.
b=5+x
but a/q,

16+x=4×(x-2)
so, 16+x=4x-8
3x=24
so, x=8.
so, present age of a=16+x=16+8=24 yrs.
Thanks
