Correct Option: D
Let the original number of employees be 100 and wages per head be ₹100.
Total wages = ₹(100 × 100) = ₹10000
New number of employees = 125
New wages per head = ₹75
Total new wages = ₹(125 × 75) = ₹9375
Decrease
= ₹(10000 – 9375) = ₹625
∴ Percentage decrease
| = | × 100 | 10000 |
| = | = | % | ||
| 100 | 25 |
