Let , x-5,x-3,x-1,x+1,x+3,x+5
,these are the 6 consecutive even numbers such that there sum is 25.
As, average is given as, bye adding each given no. above:
(6x/6)=25 =x=25
Therefore, 6 consecutive even no.s are :
20,22,24,26,28,30
Now, sumof the first three no.s are :
20+22+24=66(Ans)
Hope this will help you.
Thank you.
