    Explanation:

    Minimum number of chocolates are possible when he purchases maximum number of costliest chocolates.

    Thus, 2 x 5 + 5 x 2 =Rs.20

    Now Rs.100 must be spend on 10 chocolates as 100 = 10 x 10.

    Thus minumum number of chocolates = 5 + 2 + 10 = 17

    Hence, option 3 is the correct answer.
