Question

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

___

Answer 1

Let us assume the initial salary= 100

∵ When increased salary is 110, then initial salary is 100.

∴​When increased salary is 1, then initial salary is $\frac{100}{110}$.

∴​When increased salary is 154000, then initial salary is $\frac{100}{110}$ ×​ Rs.154000 = Rs. 140000
