Initial number (N) = 30000
Increases: 10%, 20%, 30%
Formula used:
New number after increase = N × (1 + increase in %)
Calculation:
After 10% increase:
⇒ 30000 × (1 + 10/100)
⇒ 30000 × 1.10 = 33000
After 20% increase on new number:
⇒ 33000 × (1 + 20/100)
⇒ 33000 × 1.20 = 39600
After 30% increase on new number:
⇒ 39600 × (1 + 30/100)
⇒ 39600 × 1.30 = 51480
Overall increase = 51480 - 30000 = 21480
Percentage increase = (21480 / 30000) × 100
⇒ (21480 / 30000) × 100 = 71.6%
∴ The correct answer is option (3).
