Direction (1-5) :

Number of staffs in Reserve Bank of India in 2015 = 25000

Number of staffs in Reserve Bank of India in 2014 = 20000

Increase = 25000 â€“ 20000 = 5000

Increase % = 5000/20000 Ã— 100 = 25%

Total number of staffs in State Bank of India in 2014 = 15000

Number of females staffs = 25% of 15000

= 25/100 Ã— 15000 = 3750

Number of male staffs = 15000 â€“ 3750

= 11250

Difference between the numbers of staffs in Reserve Bank of India & Number of staffs in State Bank of India for the year

2011 â€“ (20000 â€“ 10000) = 10000

2012 â€“ (25000 â€“ 15000) = 10000

2013 â€“ (35000 â€“ 25000) = 10000

2014 â€“ (20000 â€“ 15000) = 5000

2015 â€“ (30000 â€“ 25000) = 5000

2016 â€“ (35000 â€“ 20000) = 15000

Difference was highest in year 2016

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) â€“ (130/6)

= 15/6= 2.5*1000

= 2500

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

?= 11.3

? = (21.5 * 10)1/3 + (43 * 6)1/2

? = (215)(1/3) + (258)(1/2)

? = (63)(1/3) + (162)(1/2)

? = 6 + 16 = 22

40 * (440/100) + ?/100 * 655 = 228
