Question

the average of 60 numbers is 38 if two numbers namely 45 and 55 are discarded the average of remaining number is​

Answer 1

Step-by-step explanation:

The average of 50 numbers is 38  

We know that,

Here, total = 50 and average = 38

The sum of all the 50 numbers are = 50×38 = 1900

The Sum of the given two numbers = 45+55 = 100

After discarding two numbers, total numbers left now are = 48

The total sum of the remaining 48 numbers are = 1900-100 = 1800

∴  The remaining average of the 48 numbers are

Thus, the average of the remaining numbers will be 37.5.
