Directions : Study the following bar chart carefully and answer the questions given beside.
 
The following bar graph gives the information about the number of staffs recruited (in thousand) in three different banks A, B and C in six consecutive years. 

1
What is the difference between the average number of staffs recruited by the Bank A over all the years together and that by Bank C over all the years together?
» Explain it
C
The sum of the staffs recruited by the bank A over all the years together = 12 + 60 + 75 + 30 + 8 + 4.5 = 189.5 thousand

The sum of the staffs recruited by the bank C over all the years together = 13 + 50 + 60 + 35 + 6 + 12 = 176 thousand

The reqd. difference of average

189.5  –  176  =  189.5 – 176  =  13.5  = 2.25 thousand
6 6 6 6

Hence, option C is correct.
2
The number of staffs recruited by Bank B in the year 2012 and 2017 together was what percentage of the number of staffs recruited by that bank in all other years together?
» Explain it
D
The sum of the staffs recruited by the bank B over all the years together = 14 + 85 + 40 + 15 + 10 + 7 = 171 thousand

The number of staffs recruited by Bank B in the year 2012 and 2017 together = 7 + 14 = 21 thousand

the number of staffs recruited by that bank in all other years together = 171 – 21 = 150 thousand

The reqd. % =  21 × 100  = 14%
150

Hence, option D is correct.
3
The total number of staffs recruited in the year 2013 by all the three banks together was what percent more than that in the year 2014 by all the three banks together?
» Explain it
A
The total number of staffs recruited in the year 2013 by all the three banks together = 60 + 85 + 50 = 195 thousand

The total number of staffs recruited in the year 2014 by all the three banks together = 75 + 40 + 60 = 175

The reqd. % =  (195 – 175) × 100  =  20 × 100  =  80  % = 11  3  %
175 175 7 7

Hence, option A is correct.
4
If 40% of the staffs recruited in the year 2015 in the bank C was female and 70% of the total number of staffs recruited in that year by all the three banks together was male then in that year, what was the total number of females recruited by the bank A and B together?
» Explain it
D
The number of staffs recruited in the year 2015 in the bank C = 35 thousand 
 
Number of females recruited by bank C = 40% of 35 = 14 thousand 
 
The total number of staffs recruited in the year 2015 by all the three banks together = 30 + 15 + 35 = 80 thousand 
 
Number of males = 70% of 80 thousand = 56 thousand males 
 
The total number of males in the bank C = 35 – 14 = 21 thousand 
 
The total number of males in the bank A and B together = 56 – 21 = 35 thousand 
 
The total number of females in the bank A and B together = (30 + 15) – 35 = 45 – 35 = 10 thousand  

Hence, option D is correct.
5
The respective ratio of the number of females recruited in the bank A over all the years together to the number of males recruited in the bank B over all the years together was 4 : 5. In the bank B, 40% of the total number of staffs recruited over all the years together was females,  then what was the total number of males recruited by the bank A over all the years together?
» Explain it
C
The sum of the staffs recruited by the bank B over all the years together = 14 + 85 + 40 + 15 + 10 + 7 = 171 thousand

Let the number of females recruited in the bank A over all the years together = 4x then

the number of males recruited in the bank B over all the years together = 5x = (100 – 40)% of 171 = 60% of 171 = 102.60 thousand

x =  102.60  = 20.52
5

Let the number of females recruited in the bank A over all the years together = 4x = 4 × 20.52 = 82.08 thousand

The sum of the staffs recruited by the bank A over all the years together = 12 + 60 + 75 + 30 + 8 + 4.5 = 189.5 thousand

The number of males = 189.5 – 82.08 = 107.42 thousand

Hence, option C is correct.
