Here are the solutions to the problems: 22. A man bought the following items from the market. | Item | Qty | Amount | |-------|-----------|---------------| | Milk | 2 litres | 1400 @ litre | | Meat | 1 1/2 kg | 10,000 @ kg | | Sugar | 750 g | 3200 @ kg | | Bread | 2 loaves | 3500 @ loaf | a) How much money did he spend altogether? Step 1: Calculate the cost of each item. • Milk: $$ \text{Cost of Milk} = 2 \text{ litres} \times 1400 \text{ per litre} = 2800 $$ • Meat: $$ \text{Cost of Meat} = 1\frac{1}{2} \text{ kg} \times 10,000 \text{ per kg} = 1.5 \times 10,000 = 15,000 $$ • Sugar: Convert grams to kilograms: $750 \text{ g} = 0.75 \text{ kg}$ $$ \text{Cost of Sugar} = 0.75 \text{ kg} \times 3200 \text{ per kg} = 2400 $$ • Bread: $$ \text{Cost of Bread} = 2 \text{ loaves} \times 3500 \text{ per loaf} = 7000 $$ Step 2: Sum the costs of all items to find the total amount spent. $$ \text{Total spent} = 2800 + 15,000 + 2400 + 7000 $$ $$ \text{Total spent} = 17,800 + 2400 + 7000 $$ $$ \text{Total spent} = 20,200 + 7000 $$ $$ \text{Total spent} = 27,200 $$ He spent $\boxed{27,200/=}$ altogether. b) If he had a note of 50,000/=, how much was his change? Step 1: Identify the amount paid and the total amount spent. $$ \text{Amount paid} = 50,000/= $$ $$ \text{Total spent} = 27,200/= $$ Step 2: Subtract the total spent from the amount paid to find the change. $$ \text{Change} = \text{Amount paid} - \text{Total spent} $$ $$ \text{Change} = 50,000 - 27,200 $$ $$ \text{Change} = 22,800 $$ His change was $\boxed{22,800/=}$.
