Question

Sanjay gets fixed monthly income. Every year there is a certain increment in his salary. After 4 years, his monthly salary was Rs. 4500 and after 10 years his monthly salary became 5400 rupees, then find his original salary and yearly increment.

Answer 1

Answer:

Original Salary = Rs 3900 per month

Yearly increment = Rs 1800

Step-by-step explanation:

Let say His original Salary was = Rs A per month

Let say his annual incement was 12D  Rs

Then his monthly increase every year = D  Rs

Monthly salary after 4 years  A + 4D = 4500

& Monthly salary after 10 Years = A + 10D = 5400

=> 6D = 900

=> D = 150

=> 12D = 150*12 = 1800 Rs

Yearly increment = Rs 1800

A + 10*150 = 5400

=> A = 3900

Original Salary = Rs 3900 per month
