Question

The age of A is 5 years more than that of B 5 years ago the of their ages was 3:2 find their present ages in years​

Answer 1

Answer:

A = B + 5

Also,

(A-5) / (B-5) = 3/2

Putting the value of A,

Or, {(B+5) -5}/(B-5) = 3/2

Or, B/B-5 = 3/2

Or, B = 3/2(B-5)

Or, B÷3/2 = B-5

Or, B×2/3 = B-5

Or, B = 2B/3+5

Or, B = 2B/3 + 15/3

Or, B = (2B+15) /3

Or, 3B = 2B + 15

Or, 3B-2B = 15

Or, B = 15

So,

A = B + 5 = 15+5 = 20

Present ages: A = 20yrs, B = 15yrs
