The product of the ages of Zahra and Ayesha is 195. If Zahra is younger than Ayesha, what is Ayesha’s age?
- 13 years
- 15 years
- 15 years
- None of these
Explanation
Let Zahra’s age = x, Ayesha’s age = y. Then 𝑥 × 𝑦 = 195
x×y=195. Factor pairs of 195: (1,195), (3,65), (5,39), (13,15).
Since Zahra is younger, Zahra = 13, Ayesha = 15.
