Question
The average of 6 values is 40. If two more values with an
average of 'x' are added, the overall average increases by 20%. Find the value of 'x'.Solution
ATQ,
Sum of 6 values = 6 × 40 = 240
New average of all the numbers = 40 × 1.2 = 48
So, sum of 8 numbers = 48 × 8 = 384
So, average of two new numbers = (384 - 240) ÷ 2 = 72
