(1) Total of 2007 is 345 while in 2009 it crosses 690.
(2) The number of employees in research is 75 for the years 2007 and 2012.
(3) The value of the number of employees in production is greater than half the total number of
employees in the company for every year after 2008. Hence, option (d) is correct.
(4) Visual inspection gives 2011 as the correct answer.
(5) If we look at the first years numbers, we will get that the total number of employees in 2007 are
345. 10% of this being 34.5 marketing is the only department that can satisfy the below 10% for all
year’s condition. Checking the percentage for number of employees in marketing as a percentage
of the total number of employees between 2008 to 2012, we get that the percentage of marketing
employees is below 10% for each of these years. Hence, option (a) is correct.
(6) Take the weighted average. It can be seen that the approximate ratio of boys to girls is 4 :1.
Hence, using allegation, the answer will be
60
4
70
62%
1
(7) The number of girls in Business Management is 50, while the number of boys is 110. That gives us
2.2 boys per girls. For the other courses, this ratio is higher than 2.2. For example for computers,
we have 218 boys to 43 girls- roughly 5 boys per girl and so on. Note that, the ratio of boys to girls
would be a calculation for the percentage of girls studying a course. The lower the number of boys
per girl, the higher would be the percentage of girls in the course.
(8) Number of students in computers = 261. Number of students doing Business Management = 160
Thus, the number of students doing computers is greater than the number of students doing
business management by 101/160 = 63.1%
(9) 25/85 = 5/17 =30% (approx). Hence, none of these.
(10) Total number of boys = 611. Total number of girls = 145. The number of boys is greater than the
number of girls by 321.4%
