Question

The ages of rahul and haroon are in the ratio 5:7 four years later the sum of their ages will be 56 years.what are their present ages?

Answer 1

ages of rahul and haroon = 5:7.

after 4 years,

rahul will be 5x+4.

haroon will be 7x+4.

so according to statement,

5x+4+7x+4 = 56.

12x + 8 = 56.

12x = 56 - 8.

x = 48 ÷ 12.

x = 4.

so,

rahul = 5x = 5 × 4 = 20 years.

haroon = 7x = 7 × 4 = 28 years.

hope it helps u......
