Question
The product of two positive numbers is 192. If one of
the numbers is twice 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 = 2 × x = '2x'
So, x × 2x = 192
Or, 2x² = 192
Or, x² = 96
Or, x = 9.8 {Since the numbers are positive}
Required difference = {2 × (9.8) - 9.8} = (19.6 - 9.8) = 9.8
