Answer:

1. What percent of 50 is 30?

R = 60℅

2. What is 50% of 120?

P = 60

3. There are 40 students in a class. Ninety(90) percent of them are present. How many are present?

P = 36

4. In a basket of apples, 12% of them are rotten and 66 are in good condition. Find the total number of apples in the basket.

B = 550

Solution:

1. What percent of 50 is 30?

• R = P ÷ B

• R = 30 ÷ 50

• R = 0.6 × 100

• R = 60℅

2. What is 50% of 120?

• P = B × R

• P = 120 × 50℅

• P = 120 × 0.5

• P = 60

3. There are 40 students in a class. Ninety(90) percent of them are present. How many are present?

• P = B × R

• P = 40 × 90℅

• P = 40 × 0.9

• P = 36

4. In a basket of apples, 12% of them are rotten and 66 are in good condition. Find the total number of apples in the basket.

• B = P ÷ R

• B = 66 ÷ 12℅

• B = 66 ÷ 0.12

• B = 550
