Question

The sum of 3consecutive multiples of 12 is 324.what are the multiples

Answer 1

Let number are 12x, 12(x + 1) and 12(x + 2)



According to the question :


12x + 12(x + 1) + 12(x + 2) = 324

12(x + x + 1 + x + 2) = 324

3x + 3 = 27

3x = 24

x = 8



Hence, multiples are

12x = 12(8) = 96
12(x + 1) = 12(9) = 108
12(x + 2) = 12(10) = 120

Answer 2

Hey

Here is your answer,

Let the three consecutive multiples of 12 be x , x+12 , x + 24

Given that,

The sum of 3 consecutive multiples of 12 is 324

X + x + 12 + x + 24 = 324
3x + 12 = 324 - 24
3x + 12 = 300
3x = 300 - 12
3x = 288
X = 288/3
X = 96

Therefore ,
X = 96
X + 12 = 96 + 12 = 108
X + 24 = 96 + 24 = 120

So, the three consecutive numbers are 96 , 108 and 120.

Hope it helps you!
