At present, Ritika’s age is 3 times the age of Vipul. After 7 years, Ritika will be 2 times as old as Vipul. What is the present age of Ritika (in years)?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 i.e. 21.
Let Vipul's current age be = x years
3x + 7 = 2(x + 7)
⇒ 3x + 7 = 2x + 14
⇒ x = 7
Ritika's present age = 3 × 7 = 21 years
