Write the ratio of the heights of the highest peak and the lowest peak.

  • 22 : 15

  • 15 : 22

  • 20 : 13

  • 13 : 22

Solution

A.

22 : 15

Ratio of the heights of the highest peak and lowest peak
    = 8800 : 6000 = 22 : 15

A bar graph showing the heights of six mountain peaks. Study the bar graph and answer the questions.

A bar graph showing the heights of six mountain peaks. Study the bar g
The average height of all the peaks (in m) is

  • 7601.5

  • 7600

  • 7599.5

  • 7610

Solution

B.

7600

Average height of all the peaks
  equals space fraction numerator 8200 space plus space 6000 space plus space 8600 space plus space 7500 space plus space 8800 space plus space 6500 over denominator 6 end fraction equals space 45600 over 6 space equals space 7600

A bar graph showing the heights of six mountain peaks. Study the bar g
Which peak is the second highest?

  • B

  • C

  • A

  • E

Solution

B.

C

Clearly, it indicates from the graph that Peak B (8600) is the second highest.

A bar graph showing the heights of six mountain peaks. Study the bar graph and answer the questions.

A bar graph showing the heights of six mountain peaks. Study the bar g
When the heights of the given peaks are written in ascending order, what is the average of the middle two peaks?

  • 7950 m

  • 7560 m

  • 7650 m

  • 7850 m

Solution

D.

7850 m

Heights of the peaks in ascending order
 = 6000, 6500, 7500, 8200, 8600, 8800
∴  Average of the middle two peaks
     equals space fraction numerator 7500 space plus space 8200 over denominator 2 end fraction space equals space 7850

A watch company produces four different products. The sale of these products in lakhs during 2005 and 2010 are shown in the following bar diagram. Study the graph and answer the questions. 



The sales in percentage of wrist watch in 2010 more than the sales of table clock in 2010 was nearly by

  • 26.7%

  • 27.7%

  • 28.7%

  • 21.7%

Solution

C.

28.7%

Number of wrist watches sold in 2010 = 28.7 lakhs
Number of table clocks sold in 2010 = 22.3 lakhs 
∴ Required per cent
   equals space open parentheses fraction numerator 28.7 space minus space 22.3 over denominator 22.3 end fraction close parentheses cross times space 100 equals space fraction numerator 6.4 over denominator 22.3 end fraction space cross times space 100 space equals space 28.7 percent sign
