The average of five numbers is 612. If the average of the first two numbers is 418 and the average of the last two numbers is 521, find the third number.
Show answer & explanation
Correct answer: B
Explanation
The correct answer is Option 2 i.e. 1182.
Total of 5 numbers = 612 × 5 = 3060
First two total = 418 × 2 = 836
Last two total = 521 × 2 = 1042
Third number = 3060 - (836 + 1042) = 1182
