There are two goods that are priced at Rs 5 each and are available only in integral units. If a consumer has Rs 20, then the bundle that this consumer can afford to buy is:

Solution

✅ Correct Option: 3

Option 1: (3,3) -> Cost = 5(3) + 5(3) = Rs 30, which exceeds Rs 20.

Option 2: (4,5) -> Cost = 5(4) + 5(5) = Rs 45, which exceeds Rs 20.

Option 3: (1,3) -> Cost = 5(1) + 5(3) = Rs 20, which equals the budget.

Option 4: (5,4) -> Cost = 5(5) + 5(4) = Rs 45, which exceeds Rs 20.


Hence, Option 3: (1,3) -> Since each good costs Rs 5 and the consumer has Rs 20, the bundle (1,3) costs exactly Rs 20 (1×5 + 3×5 = 20). This is the only bundle that fits within the budget constraint of 5x + 5y ≤ 20. All other options exceed the available budget. -> correct
