An empty rectangular tank with a base area of 1200 cm square and height
100 cm is filled with water from 2 taps. One tap can fill the tank with 9 Ltr of
water per minute. While the other tap can do it at 3Ltr less per minute. In how
much time will the rectangular tank be filled ? (1 L = 1000 cm 3 )

Answer:
base =1200cm^2
height =100 cm
Volume =LX B X H
V=1200X100
v= 12,000 cm^3
V= 12 L
Let the taps be T1 and T2
Rate of T1 = 9L/min
Rate of T2 = (9-3)L / min
RT2 = 6L/min
Work in 1 minute of both taps = 15 L/min
Capacity of Tank = 12 L
Therfore , time = Capacity / Speed
Time = 12/15 = 4/5
time = 0.8 min
time = 0.8 X 60 sec
Total time = 48 seconds

Answer:

Let the taps be T1 and T2
Rate of T1 = 9L/min
Rate of T2 = (9-3)L / min
RT2 = 6L/min
Work in 1 minute of both taps = 15 L/min
Capacity of Tank = 12 L Therefore, time = Capacity / Speed
Time = 12/15 = 4/5
