Directions for Question: Study the following and answer the questions that follow.


A gas cylinder can discharge gas at the rate of 1 cc/minute from burner A and at the rate of 2 cc/minute from burner B (maximum rates of discharge). The capacity of the gas cylinder is 1000 cc of gas.

The amount of heat generated is equal to 1 kcal per cc of gas.


However, there is wastage of the heat as per follows :



@ (Include higher extremes)


Q. If both burners are opened simultaneously such that the first is opened to 90% of its capacity and the second is opened to 80% of its capacity, the amount of time in which the gas cylinder will be empty (if it was half full at the start) will be:

  • a)
    250 minutes

  • b)
    400 minutes

  • c)
    200 minutes

  • d)
    None of these

Correct answer is option 'C'. Can you explain this answer?
Verified Answer
Directions for Question: Study the following and answer the questions ...
Calculation of Gas Discharge Rates:



- Burner A discharges gas at 1 cc/minute

- Burner B discharges gas at 2 cc/minute



Capacity of Gas Cylinder:



- Capacity of the gas cylinder is 1000 cc of gas



Heat Generated and Wastage:



- Heat generated is equal to 1 kcal per cc of gas

- Wastage of heat is present



Calculating Time to Empty Cylinder:



- Initially, the gas cylinder is half full, which is 500 cc

- Burner A is opened to 90% of its capacity, which is 0.9 * 1 cc/minute = 0.9 cc/minute

- Burner B is opened to 80% of its capacity, which is 0.8 * 2 cc/minute = 1.6 cc/minute

- Total discharge rate when both burners are opened simultaneously = 0.9 + 1.6 = 2.5 cc/minute

- Time taken to empty the cylinder = 500 cc / 2.5 cc/minute = 200 minutes



Therefore, the correct answer is C: 200 minutes.
