Help me with some mock questions papers

here's the continuation for Item 5.

Item 5:

a) Determine the amount of money that Uncle Collin pays to the money lending institution monthly.

Step 1: Calculate Uncle Collin's savings.
Uncle Collin's savings are $45\%$ of the total investment of Shs 12,000,000.

$$\text{Savings} = 0.45 \times 12,000,000 = 5,400,000 \text{ Shs}$$

Step 2: Calculate the loan amount needed.
The loan amount is the total investment minus his savings.
