The average of 15 numbers is 30, while the average of 13 of these numbers is 32. If the remainnig two numbers are equal, then what is each of the two numbers?
Show answer & explanation
Correct answer: A
Explanation
The correct answer is Option 1 i.e. 17.
Total of 15 numbers = 15 × 30 = 450
Total of 13 numbers = 13 × 32 = 416
Remaining 2 numbers (equal) = 450−416 = 34
Each number = 34/2 = 17
