Question

the average of four consecutive even numbers is 27. find the largest of these numbers

Answer 1

Let four consecutive even numbers are x, x+2,x+4,x+6

27 =(x+x+2+x+4+x+6)/4

27*4=4x+12

{27*4}/4=x+3

27=x+3

27-3=x

24=x


Then, consecutive numbers are,

24,26,28,30

Answer 2

Let the numbers be x,x+2,x+4,x+6
According to the question,
(4x+12)/4=27
=>4x+12=108
=>4x=96
=>x=24
The numbers are 24,26,28,30
The largest number is 30
