If 4 x 6 = 1812 and 6 x 9 = 2718, then 7 x 6 = ?
1. A1821
2. B2428
3. C3035
4. D3642
Answer and explanation
Correct answer: A
Each operand is multiplied by 3, and the two results are written together with the second operand's value first. For 4 x 6, the second operand 6 gives 18 and the first operand 4 gives 12, making 1812. For 6 x 9, 9 gives 27 and 6 gives 18, making 2718. For 7 x 6, the second operand 6 gives 18 and the first operand 7 gives 21, so the answer is 1821.
