Answer: (3) 37.5
Explanation:-
The average of 50 numbers = 38
Then, the sum of 50 numbers = 38 x 50
= 1900

If the two numbers 45 and 55 are not considered,
Then, the sum of remaining numbers = 1900 – (45 + 55)
= 1900 – 100
= 1800

The average of remaining numbers = 1800 / 48
= 300 / 8
= 37.5

Then, the average of remaining numbers is 37.5 .
Hence, the answer is (3) 37.5.
