Question
36% of one number is equal to 24% of another number. If the
sum of both numbers is 420, what is the difference between them?Solution
ATQ,
Let the numbers be ‘x’ and ‘y’ respectively.
According to the question,
⇒ 0.36x = 0.24y
⇒ x/y = 0.24 / 0.36 = 2/3
So the numbers are in the ratio 2 : 3
Sum of the numbers = 2 + 3 = 5 units = 420
⇒ 1 unit = 420 ÷ 5 = 84
⇒ Difference = (3 – 2) units = 1 unit = 84
