In 2014, there were 30% post graduate employees in department B. In 2015, 20 employees of the same department were shifted to branch ‘PQR’. If in 2015, the percentage of post graduate employees in department B were the same, how many post graduate employees were shifted to branch ‘PQR’
Explanation:
Total number of employees in department B
= 550×20/100=110
In 2014, number of graduate employees in
department B = 110×30/100=33
In 2015, number of remaining employees
=110-20=90
In 2015, the number of graduate employees in
department B =90×30/100=27
∴ Number of shifted employees = 33-27=6
