Without performing actual addition and division write the quotient when the sum of 69 and 96 is divided by

(i) 11 (ii) 15

1) Here, we observe that 69 and 96 are having ten’s and unit place interchanged, ie they are having reverse digits.


Hence, sum of digits is 15.


We know that when ab + ba is divided by 11, quotient is (a + b).


The sum of 69 and 96 is divided by 11, we get 15 (sum of digits) as our quotient.
