MediumOriginal question

Options for question 30

Show the answer and explanation
CorrectNot quiteAnswer C

Correct answer: C

Explanation

  1. The digits of 234 multiply to the second number: 2×3×4=242 \times 3 \times 4 = 24.

  2. 3×1×5=153 \times 1 \times 5 = 15, so 315 : 15 matches.

  3. 142 : 7, 521 : 8 and 333 : 9 give the digit SUM, not the product.

Worth noting

Check both digit operations on the given pair: the digit sum of 234 is 9, not 24, so the rule must be the product.
