Question

the ratio of ages of a and b is 1:2.in 7 years hence their ratios would be 3:5 find their current ages?​

Answer 1

Answer:

let their ratios be x and 2x

So,

x+7/2x+7 = 3/5 (given)

By Cross Multiplication

5(x+7)=3(2x+7)

5x+35 = 6x+21

6x-5x=35-21

x=14

SO THEIR CURRENT AGES ARE

14 AND 14×2
