Answer 1

Hey mate
Here is your answer :--

Let the common multiple be x

1st no. = x
2nd no. = 2x
3rd no. = 3x

Given condition is :-

x+2x+3x/2 = 18
x+2x+3x = 18 × 2
6x = 36
x = 36/ 6
x = 6

Numbers are
x= 6
2x = 2×6 = 12
3x = 3×6 = 18

Hope this help you mate

Hello , here is the answer for your question :

let the numbers be x,2x,3x

Given , 1/2 ( x + 2x + 3x ) = 18

then , x+2x+3x= 36

x= 6

then , 2x = 12 and 3x = 18

∴ 6,12,18 ARE THE NUMBERS
