Question

The average of 52 numbers is 45. if two numbers, namely, 55 & 45 are discarded from the set of number, then find average of the remaining number.

Answer 1

44.8

Step-by-step explanation:

mean =45

total frequency =52

let total number be x

45=x/52

x=2340

if 55,45 are discarded

x=2340-(55+45)

x=2340-100

x=2240

mean of remaining number is 2240/50

=44.8
