Answer:
11
Step-by-step explanation:
Given, Average of 6 numbers = 10
One of the number is 5
∵ Average of n numbers = Sum of n numbers / n
⇒ 10 = S / 6 (Let S be the sum of numbers)
⇒ S = 60
∵ One number is given as 5,
∴ Sum of remaining 5 numbers = 60 - 5 = 55
Hence, average of 5 numbers = 55 / 5 = 11
