Question

The sum of present ages of Rahul and Sikha is 20 years. After 10 years, five times of Rahul's age is equal to three times of Sikha's age. Find the present age of Rahul.

• A. 5 years
• B. 10 years
• C. 12 years
• D. 15 years

Answer 1

The correct option is A 5 years

Let the present age of Rahul = x
So, present age of Sikha = 20 - x

After 10 years,
Age of Rahul = x + 10
Age of Sikha = 30 - x

5(x + 10) = 3(30 - x)
5x + 50 = 90 - 3x
8x = 40
x = 5
So, the present age of Rahul = 5 years
