Question
If the sum of two positive numbers is 37 and the
difference between these two numbers is 5, then what is the product of the two numbers?Solution
Let the numbers be ‘x’ and ‘x + 5’. Then, x + x + 5 = 37 Or, 2x + 5 = 37 Or, x = (37 – 5)/2 = 16 So, the two numbers are 16 and 21. So, the product of the two numbers = 16 × 21 = 336
