Question
The average of 50 numbers is 38. If two numbers 45 and 55 are discarded, the average of the remaining numbers is:Options :36.53737.537.52
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
This is the total sum of all 50 numbers.
Next, we subtract the two numbers that are discarded (45 and 55) from the total sum.
So, 1900 - 45 - 55 = 1800
Now, we have the total sum of the remaining 48 numbers.
To find the new average, we divide this sum by the number of remaining values.
So, 1800 / 48 = 37.5
Therefore, the average of the remaining numbers is 37.5.
