The difference between two numbers is 14 and their sum is 40. What is the product of the two numbers?
Answer & explanation
Correct answer: option 2
The correct answer is Option (2) → 351
Adding the sum and the difference gives twice the bigger number; subtracting them gives twice the smaller one.
Bigger number \(\displaystyle =\frac{40+14}{2}=27\)
Smaller number \(\displaystyle =\frac{40-14}{2}=13\)
Product \(=27\times13=351\)
The product is 351.
