Answer» Correct Answer - Option 2 : Only B Let total number of employees in the company is Q. From a : Number of employees who like coffee = 0.4Q Number of employees who like tea = 0.25Q Number of employees who like cold drink = 0.35 × 0.2Q From data we cannot find out the answer. From b : Number of employees working in marketing determent = 0.18Q Number of employees working in IT determent = 0.35Q Number of employees working in HR determent = 0.47 × 0.25Q = 0.1175 Number of employees working in content determent = 0.47 × 0.45Q = 0.2115Q Remaining working in the other department = 141 ⇒ Q – (0.18 + 0.35 + 0.1175 + 0.2115)Q = 141 ⇒ 0.141Q = 141 ⇒ Q = 1000 Hence, option b is sufficient. From C : Employees from state X = 0.2Q Employees from state X = 0.8 × 0.6Q = 0.48Q So, remaining from state Y. But from this information, we cannot find the answer. From D : Married employees = 0.6Q and unmarried employees = 0.4Q The ratio of male to female unmarried employees is 4 : 5 and ratio of married male and female employees is 3 : 4. But from this information, we cannot find the answer. |
