Question
The product of two positive numbers is 300. If one of the
numbers is five 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 = 5 × x = '5x'
So, x × 5x = 300
Or, 5x² = 300
Or, x² = 60
Or, x = 7.75 {Since the numbers are positive}
Required difference = {5 × (7.75) - 7.75} = (38.75 - 7.75) = 31
