Answers

  1. the monthly salary increased by Rs 4,620 over that two year period.

    How to get the total increased amount for the monthly salary?

    We know that first there is a 10% increase, such that after that, the monthly salary was Rs 23,100 per month.
    In if the initial monthly salary was M, we must have:
    M*(1 + 10%/100%) = M*(1.1) = Rs 23,100
    M = Rs 23,100/1.1 = Rs 21,000
    Now, to the Rs 23,100 there is another 20% increase, then the final monthly salary will be:
    Rs 23,100*(1 + 20%/100%) = Rs 23,100*1.2 = Rs27,720
    Then the difference between the final monthly salary and the initial is:
    difference =  Rs 27,720 – Rs 23,100 = Rs 4,620
    This means that the monthly salary increased by Rs 4,620 over that two year period.
