Question
Two numbers are in the ratio 5:3. After adding 4 and 7
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+4)/(3x+7) = 2/3 => 15x + 12 = 6x + 14 => 15x – 6x = 14 – 12 => 9x = 2 => x = 2/9 So, the bigger number will be, => 5x = 5 × (2/9) = 10/9
