    Ans.1) Let the number of large-size, super-size, and jumbo-size popcorn packets be 7x, 17x, and 16x respectively.
    Let the number of large-size, super-size, and jumbo-size chips packets be 6y, 15y, and 14y respectively.
    Given, 7x+17x+16x=6y+15y+14y=>40x=35y⇒xy=78
    Now, number of jumbo popcorn packets/ number of jumbo chips packets = 16x14y=(87)×(78)=1
    Hence, ratio required = 1 : 1
    Ans.2) The ratio of the number of fruits (in dozen) = 3:2:7
    The ratio of the weight of each fruit (in grams) = 120 :150: 24
    Therefore, Ratio of fruits (combined) by weight = (3 x 120) : (2 x 150) : (7 x 24) ⇒ 30 : 25 : 14
    Ans.3) Total number of apples = 5+3 = 8
    Each person got 8/3 apples
    C paid Rs 80 for 8/3 apples
    So price of one apple =80/(8/3)=80∗3/8=Rs 30
    A got 8/3 apples, so the remaining apples from what he bought =5-8/3=7/3 apple
    So A should get amount=(7/3)∗30=Rs 70
    B got 8/3 apples, so the remaining apples from what he bought=3-8/3=1/3 apple
    B should get amount=(1/3)∗30=Rs 10
    Thus A’s share =Rs 70 and B’s share =Rs 10
