💡 Analysis & Explanation

Base Assumption ▼

Let Salil's initial salary be considered as 100 units for ease of calculation.

First Variation ▼

A 15% reduction drops the salary to 85 units (100 - 15).

Second Variation ▼

A subsequent 10% raise is applied to the new base of 85. 10% of 85 is 8.5. Adding this gives a final salary of 93.5 units.

Conclusion ▼

The overall drop from the initial 100 to the final 93.5 is exactly 6.5%.
