Answer 2

Answer:

9,6,12

Step-by-step explanation:

let the numbers be 3x,2x,4x

sum of first and second numbers=5x

difference of third and second is 4x-2x=2x

sum of first and second added to difference of third and second therefore 5x+2x=21

7x=21 means x=3

therefore numbers are

first number=3x=3×3=9

second number=2×3=6

third number=4×3=12.
