Find the average of following numbers.

12, 15, 18, 14, 16, 13, 25, 28, 23, 27

Consider the following frequency distribution.

Find the median of the distribution?

The average weight of A, B and C is 60 kg. If the average weight of B and C is 50 kg and that of A and B is 53 kg, then what is the weight of B ?

The median of data in numerals is

The median of numbers 14, 7, 18, 21 and 27 is:

The mean of 40 observations was 34. Upon checking, it was found that two observations were wrongly copied as 4 and 7. If incorrect observations are replaced by the corrected values 11 and 13, then find the corrected mean.

Read the information given below carefully and answer the question that follows:

(A) If the mean of 5 numbers is 15 and then if 27 is included to the numbers, then the mean of the 6 numbers shall be 17

(B) The mean of marks of 300 students is 60, the mean of the top 100 students' marks is 80 and the mean of the last 100 students is 50, then the mean of the marks of the rest of the 100 students of the group is 60.

(C) The mean and median of 5 observations is 9 and 8 respectively, if 1 is subtracted from each observation, then the new mean and median shall be 8 and 7 respectively
