122. The bar graph shows the results of an annual examination in a secondary school in a certain year. Answer the following four questions based on this chart.
The class having the highest number of passed students, is:
Class VII = 100 + 40 = 140
Class VIII = 90 + 50 = 140
Class IX = 80 + 70 = 150
Class X = 90 + 70 = 160 (highest)
Class X is highest number of students passed.
The class having the highest number of passed students, is:
Solution:
Class VI = 80 + 70 = 150Class VII = 100 + 40 = 140
Class VIII = 90 + 50 = 140
Class IX = 80 + 70 = 150
Class X = 90 + 70 = 160 (highest)
Class X is highest number of students passed.

124. The data given in bar diagram relate to the department wise admission of 320 students to B Sc. (Honors) first year classes of a certain college in the given five subjects. Study the graph and answer the questions.
The total number of male students who got admitted in mathematics and economics as compared to the total number of female students getting admission in mathematics and economics is:
= 30 + 32
= 62
Total number of female students in Mathematics & Economics
= 20 + 34
= 54
∴ Required %
The total number of male students who got admitted in mathematics and economics as compared to the total number of female students getting admission in mathematics and economics is:
Solution:
Total number of male students in Mathematics and Economics= 30 + 32
= 62
Total number of female students in Mathematics & Economics
= 20 + 34
= 54
∴ Required %

127. The graph shows the exchange reserve of a country in difference years. Study the graph and answer the questions.
Ratio of the sum of exchange during the year 1991-92, 1992-93, 1993-94, to that during the years 1995-96, 1996-97 and 1997-98 is:
= 2640 + 3720 + 2520
= 8880
Reserve in year 1995-96, 1996-97 and 1997-98
= 3120 + 4320 + 5040
= 12480
∴ Required ratio
= 8880 : 12480
= 37 : 52
Ratio of the sum of exchange during the year 1991-92, 1992-93, 1993-94, to that during the years 1995-96, 1996-97 and 1997-98 is:
Solution:
Reserve in year 1991-92, 1992-93 and 1993-94= 2640 + 3720 + 2520
= 8880
Reserve in year 1995-96, 1996-97 and 1997-98
= 3120 + 4320 + 5040
= 12480
∴ Required ratio
= 8880 : 12480
= 37 : 52

The percentage increase in the foreign exchange reserves in 1997 - 98 over 1993 - 94 is:
Solution:
130. The graph shows the exchange reserve of a country in difference years. Study the graph and answer the questions.
The ratio of number of years, in which the foreign exchange reserves are above the average reserves, to those in which the reserves are below the average reserves is:
Note :
Years in which the foreign exchange reserves are above the average reserves = 1992-93, 1996-97, 1997-98 = 3 years
Years in which the foreign exchange reserves are below the average reserves = 1991-92, 1993-94, 1994-95, 1995-1996, 1998-1999 = 5 years
The ratio of number of years, in which the foreign exchange reserves are above the average reserves, to those in which the reserves are below the average reserves is:
Solution:
Average reservesNote :
Years in which the foreign exchange reserves are above the average reserves = 1992-93, 1996-97, 1997-98 = 3 years
Years in which the foreign exchange reserves are below the average reserves = 1991-92, 1993-94, 1994-95, 1995-1996, 1998-1999 = 5 years
