The average of 13 numbers is 14. If each number is multiplied by 4, then what will the new average be?

Correct option is B

Original average = 14 Multiplying each value by 4 multiplies the average by 4: New average = 14 × 4 = 56
Explanation of options: (a) ✘ 14 is the original average, not updated (b) ✔ Correct — multiplying each number by 4 scales the average the same way (c) ✘ 13 is irrelevant to the transformation (d) ✘ 4.4 has no relation to the operation
