Direction (Q. 1-5) : Study the following graph carefully and answer the questions given below.
Number of buildings constructed, demolished and redeveloped across various cities in a year.
What is the difference between the total number of constructions (constructed, demolished and redeveloped) in City D and that in City E ?
Required difference = 1120 – 620 = 500
What is the average number of buildings constructed across the cities ?
Required average = 1245/5 = 249
The total number of buildings constructed across the cities is approximately what per cent of that redeveloped across the cities ?
Required % = 1245/1080 x 100 = 115%
What is the approximate average number of constructions (constructed, demolished and redeveloped) in City B ?
= (250 + 165 + 130)/3 = 545/3 = 181.6 = 182
What is the ratio of the number of buildings demolished in city A to that redeveloped in city E ?
Ratio = 220, : 360 = 11 : 18
Direction (Q. 6-10) : Study the following data carefully to answer these questions. Details of two types of machine that five different companies produce are given.
Ratio of sold to unsold machines is given below.
What is the total number of P-type machines sold ?
Since the ratio of sold to unsold machines for companies is not given for each type of machines, more information is required to solve this question. Hence, the Data lnadequate should be the correct ansvver.
What is ratio of machines sold by Company Ato unsold machines of Company D ?
Required ratio = 10 : 5x 19/7 = 14 : 19
Which Company has maximum number of unsold machines ?
By the help of above the table we can conclude that for Company A it is the required value.
The average number of machines produced by all the companies together is what per cent of the unsold machines of Company E ?
Total number of machines taking all the companies together = 108.
Their average = 108/5
Required % = 108/5 x 10 = 216%
Which Company sold the maximum number of machines ?
By the help of the above table (Soln 147) we can conclude that maximum machines is being sold by Company E.
