• A. 36
• B. 24
• C. 48
• D. 30

Explanation: The combined work rate of A, B, and C together is 1/6 of the work per day. A's individual work rate is 1/12, and B's is 1/18.

• A. 5
• B. 6
• C. 8
• D. 10

Explanation: The correct answer is D. A and B together can complete 12 units of work per day (5 units by A and 7 units by B).

• A. 1/14
• B. 1/12
• C. 1/10
• D. 1/8

Explanation: The correct answer is 1/10. To solve this, consider the total days worked by A and B together, which is 6 + 8 = 14 days.

• A. 4 hrs
• B. 5 hrs
• C. 6 hrs
• D. 7 hrs

Explanation: To solve this problem, determine the individual filling rates: A fills 1/5 of the tank per hour, and B fills 1/10 of the tank per hour.

• A. 4:1
• B. 3:2
• C. 2:1
• D. 1:2

Explanation: To find the efficiency ratio of A to B, consider the total work done as 1 task.

• A. 27
• B. 30
• C. 36
• D. 24

Explanation: The correct answer is 27 days. To solve this, first understand the efficiency relationship: B is 50% less efficient than A, so if A's work…

• A. 3.2
• B. 4
• C. 4.8
• D. 5

Explanation: To solve this problem, calculate the rate of each pipe: Pipe A fills the tank at a rate of 1/8 per hour, Pipe B fills it at 1/6 per hour…

• A. 10 hrs
• B. 20 hrs
• C. 12 hrs
• D. 8 hrs

Explanation: To find the net fill time, calculate the rates of the pipes. The first pipe fills the tank at a rate of 1/4 of the tank per hour.

• A. 24
• B. 30
• C. 36
• D. 48

Explanation: The correct answer is 24 days. If C completes the work in 12 days at a rate of 2 units per day, the total work is 24 units.

• A. Time
• B. Area
• C. Efficiency
• D. Volume

Explanation: Work done is directly proportional to efficiency because efficiency measures how effectively a task is performed.
