Question

EXERCISE 8.2
1. A man got a 10% increase in his salary. If his new salary is 1,54,000, find his
original salary.​

Answer 1

Answer:

Previous salary = x

Increase percent = 10%

New Salary = 154000

so..

x+(10/100*x)= 154000

10/100*x = 154000-x

10x/100= 154000-x

x/10 = 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 = 1,40,000

so...Original Salary was : 1,40,000
