Question

the salary of a person was increased by 15%. If his salary now is ₹9936, what was his initial salary​

Answer 1

Answer:

Step-by-step explanation:

Let Original salary of man be Rs x

Current salary of man = Rs 9936

Thus, change in salary = Rs (9936 - x)

Percent increase = 15%

We know that,

% increase = (Amount change/Original amount) x 100

or  15 =  (100)(9936 - x)/x

or (9936 - x)/x  =  15/100

or 100(9936 - x) = 15 x

or 993600 - 100 x = 15 x

or 115 x = 993600

or x = 8640

Thus initial salary of man was Rs 8640

Answer 2

Answer Explanation:

Let the initial salary be Rs.x

Final Salary = Rs.9936

Increase Percentage in the salary = 15%

Therefore, Amount of money added to the initial salary / Increase in money = Rs (15*x)

= Rs.15x

Therefore, x + 15x will give us the final salary, that is, Rs.9936

A.T.P - (equation)

x + 15x = 9936

=) 16x = 9936

=) x = 9936/16

=) x = 621

Thus, Initial Salary = x

                              = Rs.621

ANSWER:

The initial salary of the person is Rs.621.
