Answer:
B.
Base Rate Percentage
1. 60 20℅ 12
2. 65 20℅ 13
3. 80 35℅ 280
4. 320 75℅ 240
5. 25 5℅ 1.25
6. 52 50℅ 26
Solution:
1. Finding the base
• To find base (B = P ÷ R)
• B = P ÷ R
• B = 12 ÷ 20℅
• B = 12 ÷ 0.2
• B = 60
2. Finding the rate
• To find rate (R = P ÷ B)
• R = P ÷ R
• R = 13 ÷ 65
• R = 0.2 × 100
• R = 20℅
3. Finding the percentage
• To find percentage (P = B × R)
• P = B × R
• P = 80 × 35℅
• P = 80 × 0.35
• P = 280
4. Finding the base
• To find base (B = P ÷ R)
• B = P ÷ R
• B = 240 ÷ 75℅
• B = 240 ÷ 0.75
• B = 320
5. Finding the rate
• To find rate (R = P ÷ B)
• R = P ÷ B
• R = 1.25 ÷ 25
• R = 0.05 × 100
• R = 5℅
6. Finding the percentage
• To find percentage (P = B × R)
• P = B × R
• P = 52 × 50℅
• P = 52 × 0.5
• P = 26
