(i) 27 

Result 1 

Thought Number = 27 

Number obtained after reversing its digits = 72

Total of both = 27 + 72 = 99 

Dividing received number by 11 = 99/11 = 9 

Result = remainder is zero (0) . 

Result 2 

Thought Number = 27 

Number obtained after reversing its digits = 72

Subtracting small number from large number we get = 72 – 27 = 45 

Dividing received number by 9 = 45/9 = 5 

Result = remainder is zero (0) 

(ii) 67 

Result 1 

Thought Number = 67 

Number obtained after reversing its digits = 76 

Total of both = 143 

Dividing received number by 11 = 143/11 = 13 

Result = remainder is zero (0) 

Result 2

Thought Number = 67 

Number obtained after reversing its digits = 76 

Subtracting small number from large number = 76 – 67 = 9 

Dividing received number by 9 = 9/9 = 1 

Result = remainder is zero (0) 

(iii) 94 

Result 1 

Thought Number = 94 

Number obtained after reversing its digits = 49 

Total of both Number = 94 + 49 = 143 

Dividing received number by 11 = 143/11 = 13 

Result = remainder is zero (0) 

Result 2 

Thought Number = 94 

Number obtained after reversing its digits = 49 

Subtracting small number from large number = 94 – 49 = 45 

Dividing received number by 9 = 45/9 = 5 

Result = remainder is zero (0)
