Question

the salary of an employee is increased by 15% .if his new salary is 12,650 , what was his salary before increment.​

Answer 1

Answer:

Rs.11000

Step-by-step explanation:

Let the old salary be Rs.x

Increment=15% of x

=15/100×x=15x/100=3x/20.

Old salary=12650-3x/20

x=12650-3x/20

x=(253000-3x)/20

20x=253000-3x

20x+3x=253000

23x=253000

x=253000/23=11000.

The salary before increment was Rs.11000 .

Answer 2

now to find his initial salary -

Salary increased by 15%,

115/100=23/20

20=original salary

23=increase salary

23=12650

1=550

20=11,000
