Question
The product of two positive numbers is 720. If one of the
numbers is four times the other, then find the difference between the given two numbers.Solution
ATQ,
Let us assume one of the numbers is 'x'
Then, another number is = 4 × x = '4x'
So, x × 4x = 720
Or, 4x² = 720
Or, x² = 180
Or, x = 13.4 {Since the numbers are positive}
Required difference = {4 × (13.4) - 13.4} = (53.6 - 13.4) = 40.2
