Answer 1

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

Answer:21,23 and 27

Solution:-

Let the numbers be 3x,(3x+3) and (3x+6)

Then A/Q,

3x+(3x+2)+(3x+6)=72

9x+8=72

9x=63

x=7

Therefore

•3x=3×7

=21

•3x+2=21+2

=23

•3x+6=21+6

=27

________

The numbers are 21,23 and 27

Answer 2

Answer:

Suppose the number = 3x

3x + ( 3x + 2 ) + ( 3x + 6 ) = 72

9x + 8 = 72

9x = 72 - 8

9x = 63

X= 7

So ,

3x = 3 × 7

= 21

3x + 2 = 21 + 2

= 23

3x + 6 = 21 + 6

= 27

So, Answer = 21 , 23 , 27.
