To solve the problem of finding the percentage of each number, we need to calculate each percentage step by step. The formula to find a percentage of a number is:
\[
\text{Percentage of a Number} = \left( \frac{\text{Percentage}}{100} \right) \times \text{Number}
\]
Let's solve each problem one by one.

1. 20% of 60
\[
\text{20% of 60} = \left( \frac{20}{100} \right) \times 60 = 0.2 \times 60 = 12
\]
2. 30% of 90
\[
\text{30% of 90} = \left( \frac{30}{100} \right) \times 90 = 0.3 \times 90 = 27
\]
3. 15% of 60
\[
\text{15% of 60} = \left( \frac{15}{100} \right) \times 60 = 0.15 \times 60 = 9
\]
4. 40% of 30
\[
\text{40% of 30} = \left( \frac{40}{100} \right) \times 30 = 0.4 \times 30 = 12
\]
5. 24% of 50
\[
\text{24% of 50} = \left( \frac{24}{100} \right) \times 50 = 0.24 \times 50 = 12
\]
6. 10% of 100
\[
\text{10% of 100} = \left( \frac{10}{100} \right) \times 100 = 0.1 \times 100 = 10
\]
7. 50% of 50
\[
\text{50% of 50} = \left( \frac{50}{100} \right) \times 50 = 0.5 \times 50 = 25
\]
8. 10% of 60
\[
\text{10% of 60} = \left( \frac{10}{100} \right) \times 60 = 0.1 \times 60 = 6
\]
9. 77% of 100
\[
\text{77% of 100} = \left( \frac{77}{100} \right) \times 100 = 0.77 \times 100 = 77
\]
10. 45% of 60
\[
\text{45% of 60} = \left( \frac{45}{100} \right) \times 60 = 0.45 \times 60 = 27
\]
11. 35% of 40
\[
\text{35% of 40} = \left( \frac{35}{100} \right) \times 40 = 0.35 \times 40 = 14
\]
12. 55% of 20
\[
\text{55% of 20} = \left( \frac{55}{100} \right) \times 20 = 0.55 \times 20 = 11
\]
13. 40% of 90
\[
\text{40% of 90} = \left( \frac{40}{100} \right) \times 90 = 0.4 \times 90 = 36
\]
14. 30% of 80
\[
\text{30% of 80} = \left( \frac{30}{100} \right) \times 80 = 0.3 \times 80 = 24
\]
15. 40% of 50
\[
\text{40% of 50} = \left( \frac{40}{100} \right) \times 50 = 0.4 \times 50 = 20
\]
16. 25% of 20
\[
\text{25% of 20} = \left( \frac{25}{100} \right) \times 20 = 0.25 \times 20 = 5
\]
17. 20% of 50
\[
\text{20% of 50} = \left( \frac{20}{100} \right) \times 50 = 0.2 \times 50 = 10
\]
18. 80% of 95
\[
\text{80% of 95} = \left( \frac{80}{100} \right) \times 95 = 0.8 \times 95 = 76
\]
19. 55% of 40
\[
\text{55% of 40} = \left( \frac{55}{100} \right) \times 40 = 0.55 \times 40 = 22
\]
20. 12% of 400
\[
\text{12% of 400} = \left( \frac{12}{100} \right) \times 400 = 0.12 \times 400 = 48
\]
