Question

The sum of three consecutive multiples of 3 is 72. What are the multiples

Step By Step

Answer 1

Answer:

let's take 3x, 3x + 3 , 3x + 6

3x + 3x + 3 +3x +6= 72

9x + 9 = 72

9x = 72-9

x = 63 /9

x= 7

first no= 3x = 7*3= 21

second no = 3x + 3 = 21+ 3 = 24

third no = 3x + 6 = 21 + 6 = 27

Answer 2

Explanation:

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 = 240
