Step-by-step explanation:
Let,
- Amit's age be x.
- Armaan's age be y.
CASE 1: Five years ago
3×(y-5)=x-5
3y-15=x-5
3y-x=10 - - - - - - - - - equation 1
CASE 2: Ten years later
2×(y+10)=x+10
2y+20=x+10
x-2y=20-10
x-2y=10 - - - - - - - - - - equation 2
Equation 1 + Equation 2,
3y-x+x-2y=10+10
y=20
y in equation 2
x=10+40
x=50
Therfore,
Amit'age is 50 and Armaan's age is 20.
