Architect: Building:: Sculptor : ?

Explanation: As 'Architect' makes 'Building' similarly 'Sculptor' makes 'Statue'.

A and B are young ones of C. If C is the father of A but B is not the son of C. How are B and C related?

Explanation: C has two children A and B, if A is his son, B must be his daughter.

A and B invest in a business in the ratio 3 : 2. If 5% of the total profit goes to charity and A's share is Rs. 855, the total profit is:

Explanation: Let the total profit be Rs. 100.
After paying to charity, A's share = Rs. {95 x3/5} = Rs. 57.
If A's share is Rs. 57, total profit = Rs. 100.
If A's share Rs. 855, total profit = {100/57x 855} = 1500.

The average of 20 numbers is zero. Of them, at the most, how many may be greater than zero?

Average of 20 numbers = 0.
Sum of 20 numbers (0 x 20) = 0.
It is quite possible that 19 of these numbers may be positive and if their sum is a then 20th number is (-a).

Average age of employees working in a department is 30 years. In the next year, 8 workers will retire. What will be the average age in the next year?
I. Retirement age is 60 years.
II. There are 50 employees in the department.

Explanation: Given, Average age of employees = 30 years
From Statement I:
Retirement age = 60 years.
From Statement II:
Number of employees in the department = 50
=> Average age of 50 employees = 30 years.
=> Total age of 50 employees = (50 x 30) years = 1500 years
Number of employees next year = 42. (since 8 workers retire)
From Both Statements I and II:
Total age of 42 employees in the next year (1500 + 42 - 60 x 8) = 1062.
Average age in the next year = 1062/ 42 = 25.29
Therefore, Both statements I and II are necessary to answer.
