Question

Arjun is twice as old as Shreya. If five years ago his age was three times Shreya's age, then Arjun's present age is

Answer 1

Arjun is 20 years old and Shreya is 10 years old.

Explanation:

5 YEARS AGO-

Arjun: 2x-5

Shreya: x-5

NOW-

Arjun: 2x

Shreya: x

EQUATION-

2x-5=3(x-5) = 2x-5=3x-15

(add 15 on both sides)

2x+10=3x

(subract 2x from both sides)

x=10

Therefore, Arjun is 20 years old and Shreya is 10 years old :)
