Observe the bar graph carefully and answer the given questions: a) What information is given by the bar graph? b) Name the lowest of the given peaks and what is its height. c) Find the ratio of the he

Here are the solutions to questions 44 to 47.

44. Observe the bar graph carefully and answer the given questions:

From the bar graph, the heights of the mountain peaks are:

• Kanchenjunga: $8500 \text{ m}$

• Nanda Devi: $7800 \text{ m}$

• Mount Everest: $8800 \text{ m}$

• Himadri: $7800 \text{ m}$

• Nanga Parbat: $8100 \text{ m}$

• a) What information is given by the bar graph? The bar graph shows the Heights of Mountain Peaks.

• b) Name the lowest of the given peaks and what is its height. The lowest height is $7800 \text{ m}$. The lowest peaks are Nanda Devi and Himadri, with a height of $\boxed{7800 \text{ m}}$.

• c) Find the ratio of the heights of the lowest and highest peaks. Lowest height $= 7800 \text{ m}$ Highest height (Mount Everest) $= 8800 \text{ m}$ Ratio $= \frac{\text{Lowest height}}{\text{Highest height}}$

  $$\frac{7800 \text{ m}}{8800 \text{ m}} = \frac{78}{88} = \frac{39}{44}$$

  The ratio is $\boxed{39:44}$.

• d) Write down the measurement of the heights of the peaks in the ascending order. The heights in ascending order are: Himadri ($7800 \text{ m}$), Nanda Devi ($7800 \text{ m}$), Nanga Parbat ($8100 \text{ m}$), Kanchenjunga ($8500 \text{ m}$), Mount Everest ($8800 \text{ m}$).
