   View Answer

   B) 153
   Explanation:
   Let % of employees who work in HR in Delhi is x%. So
   [28/100 * 450 – x/100 * 450]/[ x/100 * 450] * 100 = 40
   Which is [(28-x)/x] * 100 = 40
   Solve, x = 20
   So % of employees who work in Software is 100 – (20+18+28) = 34%
   So required ans = 34/100 * 450
3. If number of employees in Bengaluru is 10% less than number of employees in Hyderabad, then what is the difference between number of employees who work in Accounts department in these 2 cities and who work in Finance department in these 2 cities?

   View Answer

   B) 104
   Explanation:
   Total employees in Bengaluru and Hyderabad = 2130 – (450+380+350) = 950
   So if in Hyderabad, employees is x, then in Bengaluru – 90/100 * x
   So x + 90x/100 = 950
   Solve, x = 500, so in Hyderabad = 500, and in Bengaluru = 90/100 * 500 = 450
   So required answer = [32/100 * 450 + 35/100 * 500] – [20/100 * 450 + 25/100 * 500]
   Or = 12/100 * 450 + 10/100 * 500

   Hyderabad – (25+35)/100 * 500 = 300
   Gurgaon – (22+20)/100 * 350 = 147
