IBPS SO Prelims Exam Model Paper 10

Total number of employees in a company in year 2009 = 4000 + 5500 = 9500
Total number of employees in a company in year 2010 = 5000 + 4000 = 9000
Total number of employees in a company in year 2011 = 6000 + 3500 = 9500
Total number of employees in a company in year 2012 = 5000 + 6500 = 11500
Total number of employees in a company in year 2013 = 7500 + 7000 = 14500
Percentage change in number of employees in the year,
⇒ 2009 =

(9500–8500)

8500

× 100 = 11.76%
⇒ 2010 =

(9500–9000)

9500

× 100 = 5.26%
⇒ 2011 =

(9500–9000)

9000

× 100 = 5.55%
⇒ 2012 =

(11500–9500)

9500

× 100 = 21.05%
⇒ 2013 =

(14500–11500)

11500

× 100 = 26.08%
∴ From the above, in the year 2013 the percentage change in the number of employees over the year 2012 is maximum.
