Answer 2

ANSWER :

Let the consecutive multiples be 3x, ( 3x+3 ) & ( 3x+6 )

According to question, the sum of these multiples is 54

=> 3x + ( 3x+3 ) + ( 3x+6 ) = 54

=> 3x + 3x + 3 + 3x + 6 = 54

=> 9x + 9 = 54

=> 9( x + 1 ) = 54

=> x + 1 = 6

=> x = 5

Therefore, the multiples are :

3x = 3*5 = 15

3x + 3 = 15 + 3 = 18

3x + 6 = 15 + 6 = 21

The multiples are 15,18 and 21.

Hope this helps you☺☺
