Plese explain with figure,,
A barrel full of beer has 2 taps one midway, which draws a litre in 6 minutes and the other at the bottom, which draws a litre in 4 minutes. The lower tap is normally used after the level of beer in the barrel is lower than midway. The capacity of the barrel is 36 litres. A new assistant opens the lower tap when the barrel is full and draws out some beer, As a result the lower tap has been used 24 minutes before the usual time. For how long was the beer drawn out by the new assistant?
Ans 16 mins

Step-by-step explanation:
The top tab is operational till 18 litres is drawn out
?Time after which the lower tap is usually open= 18 × 6 = 108 minutes
? Time after which it is open now = 108 – 24 = 84 minutes
? Litres drawn = 84/6 = 14 litres
? 18 – 14 = 4 litres were drawn by the new assistant.
? Time = 4 × 4 = 16 minutes.
sorry please, I don't have the figure
