If 24 is coded as 66 and 35 is coded as 88, then 47 is coded as
- A. 1111
- B. 112
- C. 1112
- D. 121
Explanation
Each digit is added to give a sum, which is then written twice, so 2 plus 4 is 6 giving 66, and 3 plus 5 is 8 giving 88. For 47 the sum is 11, which written twice gives 1111. Confirming a numeric rule on both examples before applying it is what avoids guesswork.
