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.
