Answer 1

Answer:

41

Step-by-step explanation:

answer is 41 because

50 should be there instead of 25

so the difference is 25

there are 25 values taken for the mean

so we need to add the existing mean with the quotient of no of values and the new difference

ie, 40 + 25/25

so answer is 40+1 = 41
