Arjun is twice as old as Shreya. Five years ago, his age was three times Shreya's age. Find the sum of their present ages:
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 30 years
let age of Arjun be ′x′ and age of Shreya be ′y′
then according to question x=2y−−−(1)
and five years ago
x−5=3(y−5)
x−5=3y−15
x−3y+10=0−−−(2)
using eq(1)
2y−3y+10=0
y=10
and x=20
age of Arjun is 20 and age of Shreya is 10
therefore sum of the ages = 20 + 10 = 30 years
