Answer 2

Answer:  Numbers are 12 , 20 , 28  

Step-by-step explanation:

Three numbers are in a ratio of 3:5:7

let the common multiple of ratio is x

therefore,

by given condition ,

3x + 5x + 7x = 60

             15x = 60

                 x = 60/ 15

                 x = 4

therefore,

3x = 3 * 4 = 12

5x = 5 * 4 = 20

7x = 7 * 4  = 28

12 + 20 + 28 = 60
