Question 10

The sum of two numbers is 22 and their difference is 14. Find the product of numbers.

Solution

Let, the two numbers be x and y

Given, sum of two numbers (x + y) = 22 ......... (1)

Difference of two numbers (x - y) = 14 .......... (2)

By adding the above two equations we get,

2x = 36 (or) x = 18

By subtracting the above two equations we get,

2y = 8 (or) y = 4

Product of two numbers (x $$\times$$ y) = 18 x 4 = 72

Hence, option A is the correct answer.
