Answer:
1. A/P = R × B
= 20% × 50
2. R = A ÷ B × 100
= 12 ÷ 25 × 100
= 0.48 × 100
3. R = A ÷ B × 100
= 4 ÷ 5 × 100
= 0.8 × 100
4. B = A ÷ R
= 45 ÷ 12%
5. B = A ÷ R
= 20 ÷ 4%

Answer:
1. A/P = R × B
= 20% × 50
= 10
2. R = A ÷ B × 100
= 12 ÷ 25 × 100
= 0.48 × 100
= 48%
3. R = A ÷ B × 100
= 4 ÷ 5 × 100
= 0.8 × 100
= 80%
4. B = A ÷ R
= 45 ÷ 12%
= 375
5. B = A ÷ R
= 20 ÷ 4%
= 500
