1. How many students have scored less than 40% marks in aggregate?

        (1) 30                       (2) 12                       (3) 17                       (4) 29

 

2. What is the percentage of students who have obtained 60% and more marks in Paper II over the number of students who obtained 40% and more marks in aggregate (approximately)?

        (1) 44                       (2) 40                       (3) 48                       (4) Data inadequate

 

How to attempt:
 

1. Note that the question asked is a score of 40%.

    40% marks means 20 marks out of 50.

    Students scoring less than 20 = (score 10 and above) – (score 20 and above) – (score    below 10) = 88 – 71 + 12 = 29.

 

2. First calculate number of students whi scored 60% or more in II = 31.

    Number of students scoring 40% and above in aggregate = 79.

    Hence required percentage = 31/79 × 100 = 40%.

1. The highest percentage of domestic consumption with reference to the production of coffee has been in the year during the given period.

        (1) 2001-02              (2) 2000-01              (3) 1996-97              (4) 1990-91

 

2. During the given period though the largest quantity of coffee exported has been lakh tonnes, the foreign exchange earned in dollars has been the highest in the year

        (1) 3.01, 1999-2000                          (2) 2.47, 1997-98

        (3) 3.06, 1997-98                             (4) None of these

 

3. Which one of the following statements is correct?

        (1) The domestic consumption of coffee has been consistently increasing.

        (2) The foreign exchange earned in rupees has been increasing during the period from      1990-91 to 2000-01.

        (3) The production of coffee in the country has been showing consistently upward     trend during the given period.

        (4) None of these.

 

How to attempt:
 

1. 4
We have to calculate percentage of domestic consumption with reference to the production of       coffee. This means we have to divide last column by first column.

 

By visual inspection, we see that the figure in 1990-91 is 0.54/1.70 = 1/3 approx.

In subsequent years, though the numerator remains more or less same, the denominator     increases. This means the first figure is the highest.

 

2. 2
Coffee exported is maximum at 2.47 lakh tones. Foreign exchange earned in dollars is   maximum at 477 in the year 1997-98. This is a visual question.
