11) If the imports in 1998 was Rs. 250 crores and the total exports in years 1998 and 1999 together was Rs 500 crores, then the imports in 1999 was

• 1) 320 Crore
• 2) 420 Crore
• 3) 520 Crore
• 4) 620 Crore
Ans.   B
Explanation :
The Ratio of imports to exports for the years 1998 and 1999 are 1.25 and 1.40 respectively. Let the exports in the year 1998 = Rs. x crores Then,the exports in the year 1999 = (500-x) crores => 1.25 = 250/x [because 1.25 is 1998 ratio] => x = 250/1.25 = 200 crore Thus the exports in the year 1999 were 500 - 200 = 300 crore Let the imports in the year 1999 = Rs y crore Then 1.40 = y/300 => y = 1.40*300 = 420 crore

12) What was the percentage increase in imports from 1997 to 1998

• 1) 70
• 2) 72
• 3) 74
Ans.   D
Explanation :
For calculating the percentage we will need value of exports, imports etc. We are only given with the ratio. So data in Inadequate. Note: Please note in charts questions, most probably it includes 1 or more than 1 questions which are percentage based. So please clear percentage questions before preparing it. Because this is very scoring section.

13) What is the difference between the two companies in the given years

• 1) 16000
• 2) 26000
• 3) 28000
• 4) 30000
Ans.   B
Explanation :
Please note that line graph values are given in thousands. Total production of Company X from 1997 to 2002 = 119000+99000+141000+78000+120000+159000 = 716000 Total production of Company Y from 1997 to 2002 = 139000+120000+100000+128000+107000+148000 = 742000 Difference = 742000 - 716000 = 26000

14) What is the difference between the numbers of vehicles manufactured by Company Y in 2000 and 2001

• 1) 21000
• 2) 22000
• 3) 23000
• 4) 24000
Ans.   A
Explanation :
Required Difference = 128000-107000 = 21000

15) What is the average number of vehicles manufactured by Company X over the given period

• 1) 119133
• 2) 119233
• 3) 119333
• 4) 119433
Ans.   C
Explanation :
Average number of vehicles manufactured by Company X = 1\6(119000+99000+141000+78000+120000+159000) = 119333

16) In which of the following years, the difference between the productions of Companies X and Y was the maximum among the given years

• 1) 1800
• 2) 1875
• 3) 1900
• 4) 2000
Ans.   D
Explanation :
Although if we have deep look on line chart the nwe can judge that it was in year 2000 Lets also solve it, For 1997 = (139000 - 119000) = 20000 For 1998 = (120000 - 99000) = 21000 For 1999 = (141000 - 100000) = 41000 For 2000 = (128000 - 78000) = 50000 For 2001 = (120000 - 107000) = 13000 For 2002 = (159000 - 148000) = 11000 Clearly the difference was maximum in year 2000.

17) The production of Company Y in 2000 was approximately what percent of the production of Company X in same year

• 1) 163%
• 2) 164%
• 3) 165%
• 4) 166%
Ans.   B
Explanation :
\begin{aligned} \text{Required Percentage =} \\left(\frac{128000}{78000}*100\right)\% \= 164.1 \% \end{aligned} Which is approximately 164%
