The average of 50 numbers is 38. If two numbers namely 45 and 55 are discarded, the aver- age of the remaining numbers is :Select one:a. 32.5b. 37.5c. 35d. 36
Question
Solution 1
The total sum of the 50 numbers is 50 * 38 = 1900.
When the two numbers 45 and 55 are discarded, the new total is 1900 - 45 - 55 = 1800.
The total number of numbers now is 50 - 2 = 48.
So, the new average is 1800 / 48 = 37.5.
Therefore, the correct answer is b. 37.5. Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study problem. Knowee AI StudyGPT i
