Answer:
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.
