The Ratio of 3 numbers id 2:7:1. The sum of the numbers is 30. What are the 3 numbers?

Three numbers are : 6, 21 and 3

Step-by-step explanation:

Given,

Ratio of 3 numbers is 2:7:1.

We can assume 3 numbers as : 2x, 7x and x respectively.

According to the problem:

2x + 7x + x = 30 {The sum of the 3 numbers is 30}

10x = 30

x = 3

Hence 3 numbers are, x = 3

2x = 2*3 = 6

7x = 7*3 = 21

Therefore we get three numbers as : 6, 21 and 3

Remember, you can check their ratios to cross check the correct answer.
