Question
The average of ‘x’ numbers is 18. If 40% of the numbers
are decreased by 4 and the remaining numbers are increased by 6, then find the new average of the ‘x’ numbers.Solution
ATQ,
Sum of ‘x’ numbers = 18x
New sum of the ‘x’ numbers = 18x – 0.4x × 4 + 0.6x × 6 = 19.6x
Therefore, new average = 19.6x/x = 19.6
