    The number is 63, so the quotient is 2.

    Two digit numbers divisible by 21:
    21, 42, 63, 84

    21: 2-1 = 1 * 3.5 = 3.5
    3.5*2*1 = 7 but 7 does not equal 21

    42: 4-2 = 2 * 3.5 = 7
    3.5*4*2 = 28 does not equal 42

    63: 6-3 = 3*3.5 = 13.5
    3.5*6*3 = 63 🙂

    Check:
    21(6-3)=21(3)= 63 🙂
    3.5(6)(3) = 21(3) = 63 🙂

    63: 6/3 = 2
