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/cc of gas. However, there is wastage of the heat as per the following table:
Gas discharge @
Loss of heat
0-0.5 cc/minute
10\(\%\)
0.5-1 cc/minute
20\(\%\)
1-1.5 cc/minute
25\(\%\)
1.5 + cc/minute
30\(\%\)
(include higher extremes)
Question: 1
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, the amount of time in which the gas cylinder will be empty (if it was half full at the start) will be
