Question
The average of two consecutive even numbers is 79. If the smaller number is increased by 50% and the larger number is decreased by 50%, then find the difference between the numbers obtaine
Solution
Let the two consecutive even numbers be x and x + 2.
ATQ,
x + 1 = 79 => x = 78
Required difference = 1.5 × 78 - 0.5 × 80 = 117 - 40 = 77
