6) Answer: b)
The total number of male having a favourite fruit of Orange
= >4200*(3/7)
The total number of female having a favourite fruit of Plum
= >3500*(2/7)
Required ratio = [4200*(3/7)] : [3500*(2/7)] = 9 : 5
7) Answer: d)
The total number of male having a favourite fruits of Apple and Grapes together
= >5600*(5/8) + 6400*(7/16)
= > 3500 + 2800 = 6300
The total number of female having a favourite fruits of Mango and Banana together
= >4800*(1/3) + 5500*(5/11)
= > 1600 + 2500 = 4100
Required difference = 6300 – 4100 = 2200
8) Answer: a)
The average number of female having a favourite fruits of Apple, Mango, Banana and Grapes together
= >[5600*(3/8) + 4800*(1/3) + 5500*(5/11) + 6400*(9/16)] / 4

Required % = (7700 / 10300) * 100 = 74.75 % = 75 %
10) Answer: b)
Total number of females having a favourite fruit of Plum
= >3500*(2/7) = 1000
Total number of males having a favourite fruit of Apple
= >5600*(5/8) = 3500
Required % = [(3500 – 1000) / 3500] * 100 = 71.42 % = 71 %
The total number of male having a favourite fruit of Orange
= >4200*(3/7)

1) Answer: b)
Number of staffs in Reserve Bank of India in 2015 = 25000
Number of staffs in Reserve Bank of India in 2014 = 20000
Increase = 25000 – 20000 = 5000
Increase % = 5000/20000 × 100 = 25%
2) Answer: a)
Total number of staffs in State Bank of India in 2014 = 15000
Number of females staffs = 25% of 15000
= 25/100 × 15000 = 3750
Number of male staffs = 15000 – 3750
= 11250
3) Answer: c)
Difference between the numbers of staffs in Reserve Bank of India & Number of staffs in State Bank of India for the year
2011 – (20000 – 10000) = 10000
2012 – (25000 – 15000) = 10000
2013 – (35000 – 25000) = 10000
2014 – (20000 – 15000) = 5000
2015 – (30000 – 25000) = 5000
2016 – (35000 – 20000) = 15000
Difference was highest in year 2016
4) Answer: d)
Average number of staffs in Reserve Bank of India = (10 + 15 + 25 + 20 + 25 + 35)/6
= 130/6
Average number of staffs in State Bank of India = (20 + 25 + 35 + 15 + 30 + 20)/6
= 145/6
Difference = (145/6) – (130/6)
= 15/6= 2.5*1000
= 2500
5) Answer: e)
Number of staffs in Reserve Bank of India in 2011, 2013 and 2015
= 10000 + 25000 + 25000
= 60000
Number of staffs in State Bank of India in 2012, 2014 and 2016
= 25000 + 15000 + 20000
= 60000
Total staffs = 60000 + 60000
= 120000
Number of staffs in Reserve Bank of India in 2015 = 25000
Number of staffs in Reserve Bank of India in 2014 = 20000
Increase = 25000 – 20000 = 5000
Increase % = 5000/20000 × 100 = 25%
2) Answer: a)
Total number of staffs in State Bank of India in 2014 = 15000
Number of females staffs = 25% of 15000
= 25/100 × 15000 = 3750
Number of male staffs = 15000 – 3750
= 11250
3) Answer: c)
Difference between the numbers of staffs in Reserve Bank of India & Number of staffs in State Bank of India for the year
2011 – (20000 – 10000) = 10000
2012 – (25000 – 15000) = 10000
2013 – (35000 – 25000) = 10000
2014 – (20000 – 15000) = 5000
2015 – (30000 – 25000) = 5000
2016 – (35000 – 20000) = 15000
Difference was highest in year 2016
4) Answer: d)
Average number of staffs in Reserve Bank of India = (10 + 15 + 25 + 20 + 25 + 35)/6
= 130/6
Average number of staffs in State Bank of India = (20 + 25 + 35 + 15 + 30 + 20)/6
= 145/6
Difference = (145/6) – (130/6)
= 15/6= 2.5*1000
= 2500
5) Answer: e)
Number of staffs in Reserve Bank of India in 2011, 2013 and 2015
= 10000 + 25000 + 25000
= 60000
Number of staffs in State Bank of India in 2012, 2014 and 2016
= 25000 + 15000 + 20000
