In this company, 60 per cent of the employees are males, 40 per cent are females, 80 per cent of the employees are sincere and 40 per cent of the employees are from this city – Rawalpura.

The correct answer is: E. None of these.

We can infer the following from the given information:

• 60% of the employees are male.
• 40% of the employees are female.
• 80% of the employees are sincere.
• 40% of the employees are from Rawalpura.

However, we cannot infer any of the following:

• All male employees are from out station.
• All male employees are sincere.
• 20% of female employees are not sincere.
• All female employees are from Rawalpura.

For example, it is possible that all male employees are sincere, but it is also possible that some male employees are not sincere. Similarly, it is possible that 20% of female employees are not sincere, but it is also possible that all female employees are sincere. Finally, it is possible that all female employees are from Rawalpura, but it is also possible that some female employees are not from Rawalpura.

In order to determine whether any of the above statements are true, we would need more information about the employees in the company.
