Question
The ratio between two numbers is 1:2. If each number is
increased by 8, the ratio between then become 5:6, find the difference between numbers.Solution
Let first number be x and the second number is 2x. According to the question, => (x + 8)/(2x + 8) = 5/6 => 6x + 48 = 10x + 40 => x = 2 Required difference = 2x – x = x = 2
