Determine the total number of parts in the ratio.

The ratio given is $3:5:2$.
Total parts $= 3 + 5 + 2 = 10$.

The estate is valued at N24,000,000.

Value per part $= \frac{\text{Total Estate Value}}{\text{Total Ratio Parts}}$

The question states "his wid and daughter" and a ratio of $3:5:2$. Given the three parts in the ratio, it is assumed that "wid" refers to the wife, and there is an implied third beneficiary, likely a son, in the order Wife:Son:Daughter.

• Wife's share: (3 parts) $$3 \times \text{N}2,400,000 = \text{N}7,200,000$$
• Son's share: (5 parts) $$5 \times \text{N}2,400,000 = \text{N}12,000,000$$
• Daughter's share: (2 parts) $$2 \times \text{N}2,400,000 = \text{N}4,800,000$$

The shares are:
Wife: $\boxed{\text{N}7,200,000}$
Son: $\boxed{\text{N}12,000,000}$
Daughter: $\boxed{\text{N}4,800,000}$
