    The least number, which when divided by 48, 60, 72, 108, 140 leaves 38, 50, 62, 98 and 130 remainders respectively, is

    A)  11115

    B)         15110

    C)  15120 

    D)  15210

    Correct Answer: B

    Solution :

    [b] Here 48 ? 38 = 60 ? 50 = 72 ? 62 = 108 ? 98 = 140 ? 130 = 10 Hence required number = (LCM of 48, 60, 72, 108 and 140)\[-10\] = 15120 ? 10 = 15110
