Question
Two numbers are in the ratio 5:3. After adding 3 and 5
to them respectively the ratio becomes 2:3. Find the bigger number.Solution
Let the two number’s be 5x and 3x. According to the question, => (5x+3)/(3x+5) = 2/3 => 15x + 9 = 6x + 10 => x = 1/9 So, the bigger number will be, => 5x = 5 × (1/9) = 5/9
