Direction : Study the bar chart carefully and answer the questions given beside.

Given bar graph shows the percentage of jobs held by Indians, Pakistanis and Bangladeshis in the Gulf over the different years. Study the bar graph and answer the following questions-
 
1
If the ratio of the total persons who are doing their jobs in the year 2013 and 2016 is 3:5 and the total Indians in the Gulf in 2016 are 4125, then find the total Bangladeshis in the year 2013 in Gulf.
» Explain it
C
Total persons doing their jobs in Gulf in the year 2016

= 4125 ×  100  = 15000
27.5

Total persons doing their jobs in Gulf in the year 2013
= 15000 ×  3  = 9000
5

Total Bangladeshis in the year 2013 in Gulf = 17.5% of 9000 = 1575

Hence, option (C) is correct.
 
2
If total Indians in Gulf in the year 2014 are equal to the total Pakistanis in Gulf in the year 2017, then find the ratio of Bangladeshis in Gulf in the respective years.
» Explain it
B
Let persons in 2014 and 2017 are ‘x’ and ‘y’ respectively.
 
According to the problem-
 
⇒ 45% of x = 30% of y
 
⇒ x : y  = 2 : 3
 
Required ratio-
 
⇒ 15% of x : 50% of y = 15x : 50y = 1 : 5

Hence, option (B) is correct.
3
If total persons in 2015 are three times the total Bangladeshis in 2016 and also the total Indians in the year 2015 are 5670, then find that the total Indians in the year 2015 are how much per cent more than the total Bangladeshis in the year 2016.
» Explain it
A
Total persons in 2015 = 5670 ×  100  = 16200
35

Total Bangladeshis in 2016 =  16200  = 5400
3

Required per cent =  5670 – 5400  × 100 = 5%
5400

Hence, option (A) is correct.

4
If the total Pakistanis in the year 2013 are 2250 and ratio of Pakistanis in the years 2013 and 2014 is 45:88, then find the total number of persons in the Gulf in the years 2013 and 2014 together.
» Explain it
B
Total persons in the year 2013 = 2250 ×  100  = 9000
25

Total Pakistan is in the year 2014 = 2250 ×  88  = 4400
45

Total persons in the year 2014 = 4400 ×  100  = 11000
40
 


Total persons in the Gulf in the year 2013 and 2014 together = 9000 + 11000 = 20000
Hence, option (B) is correct.
 

5
If ratio of total persons in all the given years from 2013 to 2017 is 2 : 3 : 3 : 4 : 5, then find the ratio of total Indians in the Gulf over all the given years from 2013 to 2017.
» Explain it
D
Let total number of persons in the given years be 2x, 3x, 3x, 4x and 5x respectively.
 
Required ratio-
 
⇒ 57.5% of 2x : 45% of 3x : 35% of 3x : 27.5% of 4x : 20% of 5x
 
⇒ 57.5 × 2 : 45 × 3 : 35 × 3 : 27.5 × 4 : 20 × 5
 
⇒ 115 : 135 : 105 : 110 : 100
 
⇒ 23 : 27 : 21 : 22 : 20

Hence, option (D) is correct.
