Question
A number 'X' is 60% less than number 'Y'. A third number
'Z' is (250/3) % of the difference between 'X' and 'Y'. 'Z' is how much percent more than 'X'?Solution
Let, 'Y' be '5x'.So, 'X' = 0.4 X 5x = '2x'Difference between 'X' and 'Y' = 5x - 2x = '3x'ATQ, Z = (250/300) X 3x = '2.5x'So, the required percentage = {(2.5x - 2x) /2x} X 100= (0.5x/2x) X 100 = 25%
