Quantitative Aptitude ( CCS) Average

The average of 50 numbers is 38. If two numbers namely 45 and 55 are discarded, the average of the remaining numbers is

32.5

37.5

Avg for 50 numbers is 38. the total is 38x50= 1900
the total of discarded numbers is 45+55=100.

hence the total for 48 numbers is 1900-100=1800.
the new average is 1800 / 48= 37.5

Hence, option 3 is the correct answer.
