    Find the quotient when 73 - 37 is divide by (i) 9 (ii) 4 (i) 9 (ii) 4
    Ans : Difference of 73 - 37 is to be divided by (i) 9 (ii) 4
    Let ab = 73 and ba = 37
    ∴ a = 7 and b = 3
    (i) The quotient of 73 - 37 (i.e. ab - bc) when divided by 7 is a - b i.e. 7 - 3 = 4

    (ii) The quotient of 73 - 37 (i.e. ab - ba) when divided by 4 i.e. (a - b) is 9
    (i) 9 (ii) 4
    Let ab = 73 and ba = 37
    ∴ a = 7 and b = 3
    (i) The quotient of 73 - 37 (i.e. ab - bc) when divided by 7 is a - b i.e. 7 - 3 = 4

    (ii) The quotient of 73 - 37 (i.e. ab - ba) when divided by 4 i.e. (a - b) is 9
