Question : 26

Total: 62

\frac{2}{3}

Solution:

Concept:

Use the ratio of shares to express each sister’s holding in terms of a common unit, then relate the sold portion to the given amount.

Explanation:

Let Taiwo’s share be

11x

and Kehinde’s share be

9x

Total value of the store is:

11x + 9x = 20x

Kehinde sells

\frac{2}{3}

of her share:

\frac{2}{3} \times 9x = 6x

This is sold for N720.00, so:

6x = 720 \Rightarrow x = 120

Therefore, the total value of the store is:

20x = 20 \times 120 = 2400

Answer:

N2,400.00
