In this question the we have to find the original salary after there is increment of 10% in the salary.
Let the man salary be before increment= x
There is 10% increase in the salary= x+ (10/100)x
= x + 0.1 x
= 1.1x
Increased salary = 154000
Therefore 1.1 x = 154000 x
= 154000/1.1= 1,40,000
Hence the original salary was 1,40,000
