a. 25% b. 30% c. 40% d. 45% e. 50%

Answer 1

To calculate the percentage of the total contribution that came from people who gave PKR 40 each, the contributions are found for each group, followed by calculating their percentage of the total contribution. The result is that 50% of the total contributed came from people who gave PKR 40 each.

Step-by-step explanation:

To determine what percentage of the total contribution came from people who gave PKR 40 each, we need to calculate the total contribution from each group and then find the ratio of the contribution from the PKR 40 group to the total.

If we assume there are 100 people in total (for simplicity), then:

• 30% contributed PKR 40 each, so 30 people × PKR 40 = PKR 1200
• 45% contributed PKR 20 each, so 45 people × PKR 20 = PKR 900
• The rest, which is 100 - 30 - 45 = 25%, contributed PKR 12 each, so 25 people × PKR 12 = PKR 300.

The total contribution is PKR 1200 (from PKR 40 group) + PKR 900 (from PKR 20 group) + PKR 300 (from PKR 12 group) = PKR 2400.

Now, we find the percentage of the total contribution that came from the PKR 40 group:

Percentage = (Contribution from PKR 40 group/Total contribution) × 100%

= (PKR 1200/PKR 2400) × 100%

= 50%

Thus, 50% of the total contribution came from people who gave PKR 40 each.
