Question : 10 of 100

Marks: +1, -0

Average of 14 numbers is 32. If the average of last 5 numbers is 26, then what is the average of the remaining numbers?

35.33
41.33
27.5
44.5

Solution:

Average of 14 numbers = 32
⇒ Sum of 14 numbers = 32 × 14 = 448
Average of last 5 numbers = 26
⇒ Sum of last 5 numbers = 26 × 5 = 130
Thus, sum of remaining (14-5) 9 numbers = 448 − 130 = 318
∴ Required average =

318/9 =35.33
