Question
The average of five even numbers is 66. If we replace
two of these even numbers, 84 and 92, with a single even number X, the new average decreases by 4. What is the value of X?Solution
Sum of 5 even numbers = 5 x 66 = 330 Sum of after 2 replacing even numbers by X = 330 - (84 + 92) + X = 330 - 176 + X Now Sum of 4 even numbers = (66 - 4) x 4 = 248 According the question, we get 330 – 176 + X = 248 X = 248 – 330 + 176 X = 94
