Question

the sum of three numbers is 27. The second number is three times the first, while the third is twice the first. Find their average.​

Answer 1

Answer:

9

Step-by-step explanation:

Average = (sum of the numbers)/(no. of terms)

                 = 27/3

                = 9

Answer 2

Answer:

The average of the three numbers is 9

Step-by-step explanation:

Let the 1st no. be x

The, 2nd no. = 3x

And, 3rd no. = 2x

Therefore, x + 2x + 3x = 27

=> 6x =27

=> x = 27/6 = 9/2

Now, 2nd no. = 9/2 *3 =27/2

3rd no. = 9/2 * 2 = 9

Then, Average = ( 9/2 + 27/2 + 9 ) /3

= ( 9+27+18/2 ) /3

= ( 54 /2 ) /3

= 27/3

= 9
