Question

The total of the ages of A, B and C at present, 90 years. Ten years ago, the ratio of
their ages was 1:2:3_What is the age of B at present?​

Answer 1

b= 30*2=60

because if a, b and c is 90

then b =30

and b value was 2

so 30*2=60

Answer 2

Answer:

Let the common ratio be x.

Therefore,

Sum of the ages of A,B,C=1x+2x+3x=6x

A.T.P,

6x=90

x=15

Therefore, age if B=2x=2×15=30.(ans)
