Question 182

Find the missing number if the average of all the eight numbers is 472??
623, 164, 529, 425 205, 301, 824, ??

Solution

Since the average of 8 numbers is 472,

Their sum is $$472 \times 8$$ = 3776

Sum of the given seven numbers = 623 + 164 + 529 + 425 + 205 + 301 + 824 = 3071

Sum of the given numbers + missing number = 3776

3071+ missing number = 3776

missing number = 705
