Direction: A bar graph showing the heights of six mountain peaks is given below. Study the bar graph and answer the questions.

  1. When the heights of the given peaks are written in ascending order, what is the average of the middle two peaks?
    1. 7950 m
    2. 7560 m
    3. 7650 m
    4. 7850 m
Correct Option: D

From the given bar diagram , we see
The ascending order is : 6000 < 6500 < 7500 < 8200 < 8600 < 8800

Required average =
7500 + 8200
2

Required average =
15700
= 7850 metre
