Answer :
246.4
Step-by-step explanation :
Let the numbers be a,b,c,d,e
(a+b+c+d)/5 = 250
a+b+c+d = 250×5 = 1250
Suppose average came 1250 when d = 53 . But we came to know that d ≠ 53 & d = 35.
Now , we would have to subtract the extra we added to the sum for calculating new average.
So ,
Sum of 5 numbers (when d=35) = 1250-(53-35) = 1250 - 18 = 1232
New average = new sum / 5
= 1232/5 = 246.4 ( Ans)
