Question

If a person joins his work in $2010$ with an annual salary of $Rs.30,000$ and receives an annual increment of $Rs.600$ every year, in which year, will his annual salary be $Rs.39,000$?

Answer 1

The person will get $Rs.30000$ at the end the year $2010$

And he will get the first increment of $Rs.600$ in the year $2011$

So the salary every year will form an A.P.

Salary in the year $(2009+n)=Rs.(30000+(n-1)\times 600)$

$30000+(n-1)\times 600=39000$

$n-1=15$

$n=16$

Therefore his salary will be incremented to $Rs.39000$ in the year $2025$
