The average of two consecutive even numbers is 85. If
the smaller number is increased by 20% and the larger number is decreased by 20%, then find the difference between the numbers obtaineSolution
Let the two consecutive even numbers be x and x + 2.
ATQ,
(x + x + 2)/2 = 85 => x + 1 = 85 => x = 84
Required difference = 1.2 Γ 84 - 0.8 Γ 86 = 100.8 - 68.8 = 32
