In this note, we will solve some good questions from previous XAT papers.
Mean Median Mode definitions below
Mean = Arithmetic Mean = Simple Average
Median = 50th percentile (All numbers arranged in ascending or descending order, the mid value or the average of the two mid values)
Mode = Value having the maximum frequency = Value occurring the most number of times!
We have numbers 71,76,80,82,91
a,b must be (76,80),(80,82),(76,82)
Now remainders by 3
2 for 71.
1 for 76
2 for 80
1 for 82
1 for 91
So 71 and 80
If there are (2n + 1) terms in an AP, then find the ratio of odd terms and sum of even terms.
