Back to Exercise
The bar model shows the present ages of A and B. In 10 years the ratio of their ages will be 2 : 3.
How old is A now?
- A 50
- B 30 Correct
- C 20
- D 40
Correct Answer: Option B
A = 3u, B = 5u: (3u + 10) ÷ (5u + 10) = 2 ÷ 3
9u + 30 = 10u + 20 → u = 10
A = 30 (B = 50)
Trap: 50 is B’s age.
Answer: 30
