Question

seventy-two is divided into two parts such that twelve times of first when added to the five times of second parts makes 472. Find each part.​

Answer 1

Let the numbers be x, 72-x

According to the problem,

12x + 5(72-x) = 472

12x + 360 - 5x = 472

7x = 472-360

= 112

x = 112/7

x = 16

Therefore, numbers are 16 and 56
