- Sachin is younger than rahul by 4 years.
Question 1:
Sachin is younger than rahul by 4 years. If their ages are in the respective ratio of 7:9,how old is Sachin?
A. 16 years
B. 18 years
C. 28 years
D. None of these
Feedback Let Rahul's age be x years. Then, Sachin's age = (x-7) years
x-7 / x = 7 / 9 <=> 9x - 63 = 7x <=> 2x = 63 <=> x = 31.5.
Hence, Sachin's age = ( x - 7 ) = 24.5 years.
x-7 / x = 7 / 9 <=> 9x - 63 = 7x <=> 2x = 63 <=> x = 31.5.
Hence, Sachin's age = ( x - 7 ) = 24.5 years.
