    Question

    The price of milk was increased by 15% last year and this year, there is again an increment of 12% in the price. Two years ago, the price was ₹60, now the price of the milk is ₹________.

    A.

    77.82

    B.

    78.27

    C.

    78.72

    D.

    77.28

    Correct option is D

    Given:

    Price of milk two years ago = ₹60

    Price increment last year = 15%

    Price increment this year = 12%

    Formula Used:

    New price = Old price × (1+Percentage increase100)\left (1 + \frac {\text{Percentage increase}}{100} \right )​​

    Solution:

    Price after the first increment :

    New price = 60 × (1+15100)\left (1 + \frac {15}{100}\right)​​
    New price = 60 × 1.15
    New price = ₹69

    Price after the second increment:
    New price = 69 × (1+12100)\left (1 + \frac {12}{100}\right)​​
    New price = 69 × 1.12
    New price = ₹77.28

    The current price of the milk is ₹77.28.
