Write quotient when the sum of 73 and 37 is divided by (i) 11 (ii) 10
Ans : Sum of 73 and 37 b is to be divided by (i) 11 (ii) 10
Let ab = 73
and ba = 37
∴ a = 7
and b = 3
(i) The quotient of ab + bc i.e (73 + 37) when divided by 11 is a + b = 7 + 3 = 10

(ii) The quotient of ab + ba i.e. (73 + 37) when divided by 10 (i.e. a + b ) is 11
