Question
The average of two consecutive even numbers is 73. If
the smaller number is increased by 40% and the larger number is decreased by 40%, then find the difference between the numbers obtaineSolution
Let the two consecutive even numbers be x and x + 2.
ATQ,
x + 1 = 73 => x = 72
Required difference = 1.4 × 72 - 0.6 × 74 = 100.8 - 44.4 = 56.4
