Correct Answer: Increase by 1.25%


Solution : Let the initial salary of Ramesh be 100.
After a 35% increase, the salary becomes = 135
Then, after a 40% decrease, the salary becomes = 135 – 0.40 × 135 = 81
Finally, after a 25% increase, the salary becomes = 81 + 0.25 × 81 = 101.25
So, the overall change in salary = $\frac{101.25 - 100}{100}$ × 100 = 1.25%
Hence, the correct answer is 'Increase by 1.25%'.
