A store purchased 20 sharpeners at K0.50 each. Half of the sharpeners were sold for K3.50 each. What is the value of the remaining sharpeners?

Here are the solutions for Question 10 and Question 11, using the stock information from the previous table.

Question 10:
To find the value of the remaining sharpeners, we first need to determine the total quantity of sharpeners and their unit cost from the stock table.

Step 1: Identify the total quantity and unit cost of sharpeners from the stock table.
Total quantity of sharpeners = 20 units
Cost per sharpener = K0.50

Step 2: Determine the quantity of remaining sharpeners.
Half of the sharpeners were sold, so the remaining sharpeners represent the other half.
Quantity of remaining sharpeners = $\frac{20}{2} = 10$ units

Step 3: Calculate the value of the remaining sharpeners.
The value of the remaining sharpeners is based on their original cost per unit, as they are still in stock. The K3.50 value was for the sharpeners that were sold.

$$\text{Value of remaining sharpeners} = \text{Quantity remaining} \times \text{Cost per unit}$$ $$$$
