Answer 1

Answer:

150

Step-by-step explanation:

Let the original salary be x and yearly increment be y.

After 4 years, his salary will be Rs.4500

∴x+4y=4500

⇒x=4500−4y

After 10 years, his salary becomes 5400.

∴x+10y=5400

⇒4500−4y+10y=5400

⇒y=150

Substituting the value of y in equation  we have

⇒x=4500−4×150

⇒x=4500−600=3900

Hence, his original salary was Rs.3900 and increment per year is Rs.150
