Question

The ages of A and B are in the ratio 5:3. After 6 years, their ages will be in the ratio 7:5. Then the
present age of A is

a) 9 years
c) 15 years
d) 20 years.
b) 10 years​

Answer 1

Step-by-step explanation:

let ages of A and B = 5x and 3x

then, After 6 years ages of A and B= (5x+6) and (3x+6) years.

But, ages after 6 years= 7:5

(5x+6)/(3x+6)=7/5

do cross multiplication and you"ll get the answer

age of A is 15 years.
