Noor is 8 years older than Umar. After 3 years, Umar will be one third as old as Noor. Find the present age of Umar?
Answer: 1 year
Explanation
Let's denote Umar's current age as x.
Noor's current age = x + 8
After 3 years:
Umar's age = x + 3
Noor's age = x + 8 + 3 = x + 11
According to the problem:
x + 3 = 1/3 * (x + 11)
3(x + 3) = x + 11
3x + 9 = x + 11
2x = 2
x = 1
