Question

Sachin is younger than Rahul by 7 years. If their ages are in the respective ratio of 7 : 9, how old is Sachin?

Answer 1

Let the age of Rahul be x,
then age of Sachin is x-7

Given ratio of the ages =7:9

7/9= x-7/x

➫ 7x=9x-63

➫ ➫ 63=2x

➫ ➫ x=63/2

➫ x=31.5

Age of Rahul=x=31.5 years,

Age of sachin = x-7=24.5 years

hope helped!

Answer 2

rahul's age=31years 6 months
sachin's age=24 years 6 months
