Question
The sum of two numbers is 30 while the difference
between these two numbers is 6. What is 50% of the product of the two numbers?Solution
Let the two numbers be ‘x’ and ‘y’ where x < y. Then, according to the question, y – 6 = x Or, y = x + 6 So, x + y = x + (x + 6) = 30 Or, 2x = 30 – 6 Or, x = (24/2) = 12 So, y = 12 + 6 = 18 Product of the two numbers = 18 × 12 = 216 50% of 216 = (216 × 0.5) = 108
