A MAN GOT A 10% PROFIT IN HIS SALARY. IF HIS SALARY IS RS.1,54,000, FIND HIS ORIGINAL SALARY.

Answer 1

10% of older salary + older salary =new salary
so
let the older salary be........X
ATQ
10/100*X+X=154000
110 X =154000 * 100
X=15400000/110
X=140000....RUPEES
original salary is 140000

Answer 2

Let us assume the original salary is y, then

y + 10% of y   = New salary = 154000

y+ 10y/100 = 154000

11y/10 = 154000

y = 1540000/11=  Rs 140000
