DIRECTIONS for the question:Solve the following question and mark the best possible option.
5 identical kilns can produce a total of 300 bricks per minute by running at a constant rate. How many bricks could 10 such kilns produce in 5 minutes?
A)
1000
B)
1800
C)
3000
D)
3600
C
Let the required number of bricks be B.
More kilns, more bricks (Direct proportion)
More time, more bricks (Direct proportion)
Thus, 5*1*B = 10*5*300 or, B = 10*5*300/5 or, B = 3000
