  • 1. What is the difference in Direct Recruits and Promotee Assistants? 
   A.) 210
   B.) 280
   C.) 180
   D.) 110

Answer: Option 'A'

Total number of assistance = 15% of 7000 = [(15/100) × 7000] = 1050 
Number of direct recruits = 40% of 1050 = [(40/100) × 1050] = 420
Number of promotee assistants = (1050 - 420) = 630 
Required difference = (630 - 420) = 210

  • 2. The Promotee Clerk - I is approximately what percent of that of Direct Recruit Clerk - I?
   A.) 10%
   B.) 9%
   C.) 11%
   D.) 10.5%

Answer: Option 'C'

Number of Clerk I = 19% of 7000 = [7000 × (19/100)] = 1330
Number of Direct Recruits = 90% of 1330 = [(90/100) × 1330] = 1197 
Number of Promotees = (1330 - 1197) = 133 
Required% = [(133/1197) × 100]% = (13300/1197)% = 10.8% ≈ 11%

  • 3. How many employees are supervisors? 
   A.) 1050
   B.) 1019
   C.) 1109
   D.) 1190

Answer: Option 'D'

Number of supervisors = 17% of 7000 = [7000 × (17/100)] = 1190

  • 4. How many total Direct Recruits among all types of employees are there? 
   A.) 4000
   B.) 3885
   C.) 3000
   D.) 3115

Answer: Option 'A'

Average percentage of Direct Recruits 
= 1/7(30 + 40 + 50 + 90 + 30 + 90 + 70) = 400/7%
Required total = 400/7 % of 7000 = (7000 × (400/7) × (1/100)) = 4000

  • 5. Which type of employees has maximum number of Direct Recruits? 
   A.) Clerk I & Officer I
   B.) Officer I
   C.) Clerk I
   D.) Clerk II

Answer: Option 'A'

Total percentage of Clerk I & Officer I = (19 + 8)% = 27%
Percentage of direct Recruits = 90% each 
Thus, Clerk I and Officer I together have maximum number of Direct Recruits.
