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

Answers (1)

If Rahul's age is x, Sachins age is x-7

Given

\frac{x-7}{x}=\frac{7}{9 } 

that is

\\7x=9(x-7)\\7x=9x-63//2x=63\\x=31.5

Age of Rahul is 31.5 and that of Sachin is 24.5-7=24.5
