      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
