Question

If the present ages of A and B are in ratio of 9:4 and after 7 years the ratio of the ages
will be 5:3 then find their present ages. (J15)
​

Answer 1

Answer:

A= 18, B = 8

Step-by-step explanation:

Let the ratios be in X

therefore the age will be

A = 9x

B = 4x

after 7,

9x +7 / 4x + 7 = 5/3

cross multiplication

27x + 21 = 20x + 35

solve it

you'ill get

x = 2

A= 18

B=8
