Answer 1

Answer:

Answer: 1st choice : 8, 24, 16 and the average of the three numbers is 16

Step-by-step explanation:

let these 3 numbers be represented as x, y, z

x is the first, y is the 2nd, and z is the third.

x + y + z = 48

y = 3x

z = 2x

x + 3x + 2x = 48

6x = 48

x = 8

y = 3*8 = 24

z = 2*8 = 16

Average = (x+y+z)/3 = 48/3 = 16
