Answer 1

Logic:

First digit = Sum of digits of the first number

Second digit = Result of the division

Calculations:

For 16 ÷ 4:

First digit = 1 + 6 = 7

Second digit = 16 ÷ 4 = 4

Result = 74

For 21 ÷ 7:

First digit = 2 + 1 = 3

Second digit = 21 ÷ 7 = 3

Result = 33

For 81 ÷ 9:

First digit = 8 + 1 = 9

Second digit = 81 ÷ 9 = 9

Result = 99

Similarly, for 55 ÷ 5:

First digit = 5 + 5 = 10

Second digit = 55 ÷ 5 = 11

Result = 1011

55 ÷ 5 = 1011

Hence, the correct answer is "Option 4".
