A man bought the following items from the market.

• 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: $$\text{Cost of Bread} = 2 \text{ loaves} \times 3500 \text{ per loaf} = 7000$$

He spent $\boxed{27,200/=}$ altogether.

His change was $\boxed{22,800/=}$.
