Question

The mean median and mode of given data of scores are $21,23$ and $22$ respectively. If $3$ is added to each score. What are the new values of mean median and mode respectively?

• A. $21,23,22$
• B. $24,26,25$
• C. $24,23,22$
• D. $23,21,24$

Answer 1

The correct option is B $24,26,25$

Mean is the average of the given set of data.

If the each data is increased by a value, then mean will also increase by the same value.

Median" is the "middle" value in the list of numbers.

If the middle value is increased by a value, then the median also increases by the same value.

The "mode" is the value that occurs most often.

Thus, if the value that occurs most often is increased, then mode will also increase.

Thus, ans is $24,26,25$.
