Q. The average of three numbers is 30. If one number is removed, the average becomes 25. What is the removed number?
A.
35
B.
30
C.
25
D.
20
Solution
Let the three numbers be x, y, z. (x + y + z) / 3 = 30 => x + y + z = 90. After removing one number, (x + y) / 2 = 25 => x + y = 50. Therefore, removed number = 90 - 50 = 40.
