# Level-2 Mixed Graph Practice Quiz -3 Medium

#### Directions (1 to 5 Questions): Study the following graph and answer the questions. 5.1) What is the total (approx) number of cars sold in the year 2013 if the growth rate in the total number of cars sold from 2012 to 2013 was the same as that of 2011 to 2012?
(a) 23905
(b) 210978
(c) 24189.
(4) 26623
(5) 24659

Solution: Ans A

Clue: Increase in the number of sales from 2012 to 2013 is same as 2011 to 2012

Increase in sales from 2011 to 2012  =  21568 – 19231 =2337.

Increase in sales from 2012 to 2013 is 2337

Therefore, Sales in 2013 = 21568 + 2337 = 23905

5.2) In which of the following years the ratio of the number of Maruti cars sold to the total number of cars sold was lowest?
(a) 2011
(b) 2006
(c) 2009
(d) 2008
(e) 2010

Ans B

Trick:  Use approximations and guesswork for this question to save time

2006  -> 115: 27 => 11:3   ( In 2006, no. of manufacturing cars sold Maruti cars is lowest compared to other years).

2007 -> 126: 33  => 42: 11= 4: 1

2008 -> 140: 45   => 28: 9

2009 -> 150: 60  => 5: 2

2010 -> 170: 68

2011 -> 190: 70 => 19: 7

2012 -> 215: 99 =>2: 1

5.3) What was the approximate average number of cars sold (other than Maruti Cars) in a year, taking the data of all the years together?
(a) 11231
(b) 10317
(c) 10919
(d) 8778
(e) 12117

Explanation: Ans D

Sale of Cars Other than Maruthi Cars =  Total car sales – Maruthi Car sales 8826      |   9299   |  9410   |   9313   | 10309 | 12031  | 11668

Average = (8826 + 9299 + 9410 + 9313 + 10309 + 12031 +11668)/ 7  = 61446/7  = 8778

5.4) The number of Maruthi cars sold in the years 2007, 2008 and 2009 is approximate what percent of the total number of all the cars sold in the years 2006, 2007, 2009, 2011 and 2012?
(a) 22%
(b) 25%
(c) 17%
(d) 29%
(e) 11%

Solution:  Ans C

Total no. of car sales (including Maruti cars) in 2006, 2007, 2009, 2011 and 2012 = (11526 + 12649 + 15313 + 19231 + 21568) = 80287.

Number of Maruthi cars sold in the years 2007, 2008 and 2009  = 13900.

Required Percentage = [13900/80287] * 100  = 17%

5.5) What is the ratio between the number of cars sold other than that of Maruti in 2011 to the total number of cars sold in 2006?
(a) 10: 26
(b) 10: 17
(c) 11: 4
(d) 11: 8
Solution: Ans D

Cars sold other than Maruthi cars in 2011  = (19231 -7200) =  12031

Cars sold other than Maruthi cars in 2006 = (11526 -2700) = 8826

Required Ratio = 12031 : 8826   =12000 : 8800  = 121 : 88  = 11: 8  (approximate)
