Answer 1

suppose his salary is x rs per annum.increase salary is 10% of original is equal to 154000.then his original salary will be 1540000 perannum .

Answer 2

So we know that after he got a 10% increment in his salary, it now is Rs.1,54,000
which  means x*110/100=154000
from here, we get      x = 154000*100/110
or x = 1,40,000.
now that is the salary that the had had before the increment
