Amount = 500
Increment = 20% and 25%.
Formula used
Increased amount = initial × (100 + r)/100
Calculation
After 1st increment
Amount = 500 + 20% of 500
= 500 + 100 = 600
After 2nd increment
Amount = 600 + 25% of 600
= 600 + 150 = 750
∴ Required percentage = [(750 – 500)/500] × 100 = 50%
The answer is 50%.
Hint x + y + xy/100
= 20 + 25 + 20 × 25 /100
= 45 + 5 = 50%
