Question
36% of one number is equal to 24% of another number. If
the sum of both numbers is 420, find the difference between them.Solution
Let the numbers be ‘x’ and ‘y’ respectively According to the question, 0.36x = 0.24y Or, x/y = 2/3 Therefore, (2 + 3) units = 420 Or, 1 unit = 84 Therefore, difference = 3 – 2 = 1 unit = 84
