1.Answer: c
According to the question:
3.25/export(2008) = 0.65
=> export(2008) = 3.25/0.65
=>export(2008) = 5 lakh
Now, Export(2009) = 13.8 – 5 = 8.8 lakh
Import(2009)/8.8 = 1.52
=> import(2009) = 13.376 lakh
Hence, import of the company in 2009 is 13.376 lakh.
2.answer: d
In the above line graph ratio of import to export is given and from this information we cannot calculate the values of export of the companies. Hence given data is not adequate to solve the question.
3.answer: c
The import of the company in 2008 is 11.7
The ratio of import/export in the company 2008 =65/100
11.7/export(2008) = 0.65
Export(2008) = 18
The ratio of import/export in the company 2010 =78/100
Import(2010)/ 11.7 = 0.78
Import(2010) = 9.126
Required Percentage= (18/9.126)*100 =197.238
4.answer: a
according to the question
5.6/export(2006) = 1.25
=> export(2006) = 5.6/1.25
=> export(2006) = 4.48 lakh
And
5.6/export(2011) = 2.1
=> export(2011) = 5.6/2.1 = 2.67 lakh
Required sum = 4.48 + 2.67 = 7.15 lakh
5.answer: b
according to the question:
import(2007)/7.6 = 0.72
=> import(2007) = 0.72 x 7.6
=> import(2007) = 5.472 lakh
Hence, import of the company in 2007 is 5.472 lakh
According to the question:
3.25/export(2008) = 0.65
=> export(2008) = 3.25/0.65
=>export(2008) = 5 lakh
Now, Export(2009) = 13.8 – 5 = 8.8 lakh
Import(2009)/8.8 = 1.52
=> import(2009) = 13.376 lakh
Hence, import of the company in 2009 is 13.376 lakh.
2.answer: d
In the above line graph ratio of import to export is given and from this information we cannot calculate the values of export of the companies. Hence given data is not adequate to solve the question.
3.answer: c
The import of the company in 2008 is 11.7
The ratio of import/export in the company 2008 =65/100
11.7/export(2008) = 0.65
Export(2008) = 18
The ratio of import/export in the company 2010 =78/100
Import(2010)/ 11.7 = 0.78
Import(2010) = 9.126
Required Percentage= (18/9.126)*100 =197.238
4.answer: a
according to the question
5.6/export(2006) = 1.25
=> export(2006) = 5.6/1.25
=> export(2006) = 4.48 lakh
And
5.6/export(2011) = 2.1
=> export(2011) = 5.6/2.1 = 2.67 lakh
Required sum = 4.48 + 2.67 = 7.15 lakh
5.answer: b
according to the question:
import(2007)/7.6 = 0.72
=> import(2007) = 0.72 x 7.6
=> import(2007) = 5.472 lakh
Hence, import of the company in 2007 is 5.472 lakh

1.answer: b
let C takes X hours to fill the cistern.
According to the question:
4/24 + 4/x + 5/x + 5/30 = 1
=> 1/6 + 9/x + 1/6 = 1
=> 2/6 + 9/x = 1
=> 1/3 + 9/x = 1
=> 9/x = 1-1/3
=> 9/x = 2/3
=> x = 27/2 hours
Hence, C can alone fill the cistern in 27/2 hours.
2.answer: d
let D should be closed after x hours.
x/30 + x/45 + 20/45 = 1
=> (3x+2x)/90 = 1-20/45
=> 5x/90 = (45-20)/45
=> x/18 = 25/45
=> x = 10 hours.
Hence, D should be closed after 10 hours.
3.answer: d
let time taken by B to fill the cistern = 4x hours
hence, time taken by F to fill the cistern = 2x hours
and time taken by C to fill the cistern = x hours
according to the question:
48/x + 48/2x + 48/4x = 1
=> (192 + 96 + 48)/4x = 1
=> 4x = 336
=> x = 336/4
=> x = 84 hours.
Hence, time taken by F to fill the cistern = 2 x 84 = 168 hours.
4.answer: b
part of the tank filled in 2 hours = 1/24 + 1/30 = 3/40
=>part of the tank filled in 2 x 13 hours = 3 x 13/40 = 39/40
Remaining part = 1 – 39/40 = 1/40
Since A is opened first, time taken by A to fill 1/40 part:
x/24 = 1/40
=> x = 3/5
Hence total time = 2 x 13 + 3/5 = 26(3/5) hours.
5.answer: a
let both the pipes can fill the cistern in x hours.
According to the question:
x/12 + x/(24 * 3) = 1
=> x/12 + x/72= 1
=> (6x + x)/72 = 1
=> 7/72= 1
=> x = 10 2/7 hours.
Hence, both the pipes can fill the cistern in 10 2/7 hours.
let C takes X hours to fill the cistern.
According to the question:
4/24 + 4/x + 5/x + 5/30 = 1
=> 1/6 + 9/x + 1/6 = 1
=> 2/6 + 9/x = 1
=> 1/3 + 9/x = 1
=> 9/x = 1-1/3
=> 9/x = 2/3
=> x = 27/2 hours
Hence, C can alone fill the cistern in 27/2 hours.
2.answer: d
let D should be closed after x hours.
x/30 + x/45 + 20/45 = 1
=> (3x+2x)/90 = 1-20/45
=> 5x/90 = (45-20)/45
=> x/18 = 25/45
=> x = 10 hours.
Hence, D should be closed after 10 hours.
3.answer: d
let time taken by B to fill the cistern = 4x hours
hence, time taken by F to fill the cistern = 2x hours
and time taken by C to fill the cistern = x hours
according to the question:
48/x + 48/2x + 48/4x = 1
=> (192 + 96 + 48)/4x = 1
=> 4x = 336
=> x = 336/4
=> x = 84 hours.
Hence, time taken by F to fill the cistern = 2 x 84 = 168 hours.
4.answer: b
part of the tank filled in 2 hours = 1/24 + 1/30 = 3/40
=>part of the tank filled in 2 x 13 hours = 3 x 13/40 = 39/40
Remaining part = 1 – 39/40 = 1/40
Since A is opened first, time taken by A to fill 1/40 part:
x/24 = 1/40
=> x = 3/5
Hence total time = 2 x 13 + 3/5 = 26(3/5) hours.
5.answer: a
let both the pipes can fill the cistern in x hours.
According to the question:
x/12 + x/(24 * 3) = 1
=> x/12 + x/72= 1
=> (6x + x)/72 = 1
=> 7/72= 1
=> x = 10 2/7 hours.
Hence, both the pipes can fill the cistern in 10 2/7 hours.

1.Answer: b
Sum of total number of boys, girls and teachers in school A = 250 + 125 + 15 = 390
Sum of total number of boys, girls and teachers in school D = 275 + 100 + 14 = 389
Required percentage = 390/389 x 100 = 100.25%
2.Answer: d
Total number of boys, girls and teachers in school B = 175 + 200 + 20 = 395
Total number of boys, girls and teachers in school C = 225 + 75 + 25 = 325
Required ratio = 395:325 = 79:65
3.Answer: b
Total number of boys from all the schools together = 250 + 175 + 225 + 275 + 125 + 200 = 1250
Total number of girls from all the schools together = 125 + 200 + 75 + 100 + 225 + 175 = 900
Required difference = 1250 – 900 = 350
4.Answer: a
Total number of boys, girls and teachers of school E = 125 + 225 + 26 = 376
