The average of four numbers was 44. With the inclusion of a fifth number, y, the new average dropped to 42. What is the value of y?
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 34
Average of 4 numbers = 44
⇒ Total = 4 × 44 = 176
New average with 5th number y = 42
⇒ New total = 5 × 42 = 210
y = 210 − 176 = 34
