The given multipliers are factors of 9, the possible number will have 1 as first and last digit which gives the number as 101
<h3>How can the correct number be found?</h3>
The given numbers are;
18, 27, 36, 45, 54, 63, 72, 81, 99
Given that the first and the last figures are those of the multipliers, we have;
The first and last and last digit of the number can be 1, which gives;
Possible numbers includes; 11 and 101
By trying the possible numbers, the difference found is presented as follows;
99 × 11 = 1089 (The first and the last digit are not the same as the multiplier)
- 99 × 101 = 9999 (First and last digit are not the same as the multiplier)
90 × 11 = 990
90 × 101 = 9090
The correct option is therefore 101
