Question

jatin got increase 10%in his salary if his new salary is 55000 find his previous salary

Answer 1

55000 is jatin new salary 10% increase 5500 is increased
past salary is new salary +10%=old salary
55000-5500=49500
.: old salary is 49500

Answer 2

Let previous Salary of Jatin was x

Increment = 10% (Remember increment is always calculated on Old Salary)

∴ Increment = 10% of x

Previous Salary + Increment = New Salary

x + 10% of x = 55000

x + (10/100)x = 55000

(10x + x)/10 = 55000

11x/10 = 55000

x = (55000 × 10)/11

x = 50000

∴ Previous Salary of Jatin was Rs.50000
