### Question

The sum of the ages of Musa and Lawal is 28 years. After sharing a certain sum of money in the ratio of their ages, Musa gets ₦600 and Lawal ₦800. How old is Lawal?

A) 14 years

B) 20 years

C) 12 years

D) 16 years

### Explanation:

M + L = 28,
M : L = 600 : 800
= 3 : 4
$$\frac{M}{L}$$ = $$\frac{3}{4}$$ $$\to$$ M = $$\frac{3}{4}$$L
$$\frac{3}{4}$$L + L = 28
$$\frac{7L}{4}$$ = 28
L = $$\frac{4 \times 28}{7}$$
= 16

## Dicussion (1)

• M + L = 28,
M : L = 600 : 800
= 3 : 4
$$\frac{M}{L}$$ = $$\frac{3}{4}$$ $$\to$$ M = $$\frac{3}{4}$$L
$$\frac{3}{4}$$L + L = 28
$$\frac{7L}{4}$$ = 28
L = $$\frac{4 \times 28}{7}$$
= 16
