rate – base – percentage – n

Answers:

1. Base = n

Rate = 30%

Percentage = 1.8

2. Base 400

n = 6

Rate = n%

Percentage = 240

n = 60%

3. Base = n

Rate = 30%

Percentage = 2.4

n=8

4. Base = n

Rate = 25%

Percentage = 225

n = 900

5. Base = n

Rate = 70%

Percentage = 14.7

6. Base = n

Rate = 13%

Percentage = 113

n = 869.23

7. Base = n

Rate = 28% Percentage 196 n = 700

8. Base = n

Rate = 35%

Percentage = 1200

n = 3,428.57

9. Base = n

Rate = 11%

Percentage = 175.5

n = 1,595.45

10. Base = 65

Rate = 40%

Percentage = n

hope it helps
