Question

The sum of three numbers is 100. The second number is 3 times greater than the first, and the third is 2 times greater than the second. What is the number?

Answer 1

The numbers are 10, 30, and 60.

Explanation:

Let x, y, and z be the numbers. y = 3x, and z = 2y = 6x.

x + 3x + 6x = 100

10x = 100

x = 10, y = 30, z = 60
