Answer 2

Given,

Increase percentage = 10%

New salary = ₹55000

Let the previous salary be ₹x.

New salary = Previous salary + Increase in salary

55000 = x + increase in salary

Increase in salary = 55000 - x

$percentage \: increase = \frac{increase \: in \: salary}{original \: salary} \times 100 \\ 10 = \frac{55000 - x}{x} \times 100 \\ 10x = (55000 - x) \times 10 \\ \frac{10x}{100} = 55000 - x \\ \frac{x}{10} + x = 55000 \\ \frac{11x}{10} = 55000 \\ x = \frac{55000 \times 10}{11} \\ x = 5000 \times 10 \\ x = 50000$
