⭐CORRECT QUESTION:
A man got 10% increase in his salary if his new salary is 154000. find his original salary.
☯️Given :
Increase percentage = 10%
New salary = 154000.
Let the original salary be "x"
Now,
New salary = Original salary + increase in salary
154000 = x + increase in salary
154000 - x = increase in salary
Increase in salary = 154000 - x
Now,
percentage increase = increase in salary/original salary × 100
10 =( 154000 - x / X ) × 10
=》10x = (154000 - x) × 100
=》10x/100 = 154000 -x
=》x/10 = 154000
=》x/10 + x = 154000
=》x (1/10 + 1) = 154000
=》x (1+10/10) = 154000
=》x (11/10) = 154000
=》x = 154000×10 / 11
=》x = 140000
Original salary is 1,40,000(Ans)
