Question

The sum of three consecutive multiples of 3 is 72. Find the numbers.

Answer 1

Answer:

Let the numbers be 3x, 3x + 3 and 3x + 6.

Then,

3x + (3x + 3) + (3x + 6) = 72

9x = 63

x = 7

Largest number = 3x + 6 = 27.

=> Second largest number = 27 - 3 = 24

Answer 2

Answer:

The consecutive multiples of 3 that add up to 72 is 21, 24, and 27.

Step-by-step explanation:

Let x be the first consecutive multiple of 3.

Then,

It consecutive multiple of 3 = (x + 3)

And,

It's consecutive multiple of 3 = (x + 6)

Now, according to the Question,

Sum of three consecutive multiple of 3 = 72

x + (x + 3) + (x + 6) = 72

x + x + 3 + x + 6 = 72

3x + 9 = 72

3x = 72 - 9

3x = 63

x = 63/3

x = 21

Then, the numbers will be,

x = 21

x + 3 = 21 + 3 = 24

x + 6 = 21 + 6 = 27

So,

The consecutive multiples of 3 that add up to 72 is 21, 24, and 27.
