Question
Select the correct answerThe average of 50 numbers is 38. If two numbers namely 45 and 55 are discarded, the average of the remaining numbers is?Options32.53537.536
Solution
To solve this problem, we first need to find the total sum of the 50 numbers. We do this by multiplying the average by the number of values.
So, 50 * 38 = 1900
Next, we subtract the two numbers that are discarded from the total sum.
So, 1900 - 45 - 55 = 1800
Now, we find the new average by dividing this new total by the new number of values, which is 48 (since we discarded 2 numbers from the original 50).
So, 1800 / 48 = 37.5
Therefore, the average of the remaining numbers is 37.5. The closest option to this is 37.536.
