Question

1. A man got a 10% increase in his salary. If his new salary is 71,54,000, find his
original salary.​

Answer 1

Step-by-step explanations

Given,

Increase Percentage = 10 percent

New salary = 154000

Let the original salary be x

Now,

New salary = original salary+ increase salary

154000 = x + increase salary

154000 - x = increase salary

Now,

Percentage increase = increase salary/ original salary * 100

10 = 154000/x * 100

10x = ( 154000 - x) * 100

10x / 100 = 154000 - x

x/ 10 + x = 154000

x ( 1/10+ 1) = 154000

x ( 1+10/10) = 154000

x ( 11/10) = 154000

x = 154000* 10/11

x = 140000

original salary is Rs. 140000
