The salary of Amit is 75% of the salary of Aman. The salary of Amit increases by 40% and the salary of Aman increases by 10%. By what approximate percentage is the new salary of Aman more than the new salary of Amit ?

4.8%

Let salary of Aman = 100x

Salary of Amit = 75% of 100x = 75x

Increased salary of Amit = 75x + 40% of 75x

= 75x + 30x = 105x

Increased salary of Aman = 100x + 10% of 100x = 110x

required percentage = \(\frac{110x - 105x}{105x}\) × 100 = 4.76%

= 4.8%  (approx.)
