Find the missing number if the average of all the eight numbers is 474.

533, 128, 429, 225. . 305, 601, 804

A) 767
B) 781
C) 776
D) 753
E) None of these

Correct Answer:

A) 767

Description for Correct answer:
Let the missing number be x

Average of 8 numbers = 474

Average of 8 numbers

= \( \Large \frac{ 523 + 128 + 429 + 225 + x + 305 + 601+ 804 }{8} \)

474 = \( \Large \frac{3025 + x}{8} \)

474 X 8 = 3025 + x

3792 - 3025 = x

x = 767
