Question

median of a group of 20 distinct numbers wasfound to be 55. if largest 8 numbers areincreased by 10, then median of the new group,is-

Answer 1

Answer:

55

Step-by-step explanation:

The median is the middle value when there are an odd number of values, and it is the mean of the two middle values when there are an even number of values.

Here there are 20 numbers, so the median is the mean of the 10th and 11th numbers.

Increasing the largest 8 numbers won't change the order of the numbers, and the 10th and 11th numbers stay the same.  So the median stays the same.
