**Directions (6-10): Study the bar chart given below and answer the following questions.**

The bar chart shows the efficiencies (in liters/minute) of 6 different pipes (A, B, C, D, E & F).

** Q6. Pipe – D & E together can fill a tank in 36 minutes. Pipe – C alone starts filling the same tank and after T minutes, pipe – D & E together replaced it. If pipe – D & E together filled the remaining tank in 24 minutes, then find T.**

(a) 27.5

(b) 25

(c) 30

(d) 32.5

(e) 22.5

**Q7. Pipe – A, C & F starts filling a tank in such a way that pipe – A filled the tank in 1st and 2nd minute, then pipe – F filled the tank in 3rd minute and then pipe – C filled the tank in 4th & 5th minute. If the tank is completely filled in minutes, then find the total capacity of the tank.**

(a) 2553 liters

(b) 2560 liters

(c) 2592 liters

(d) 2577 liters

(e) None of the above.

**Q8. If pipe – D alone can fill a tank in 84 minutes and pipe – G is 40% more efficient than pipe – B, then find the time taken by pipe – F & G together to fill the same tank.**

(a) 80 minutes

(b) 72 minutes

(c) 33⅓ minutes

(d) 60 minutes

(e) 66⅔ minutes

**Q9. If the total capacity of a tank is 3200 liters and pipes – B, D & E are attached to it. Pipe – B & E are filling pipes and pipe – D is an emptying pipe. If all three pipes are opened together in the tank, then in how much time the tank will be completely filled?**

(a) 120 minutes

(b) 128 minutes

(c) 112 minutes

(d) 136 minutes

(e) 148 minutes

**Q10. If pipes – A, C & P together can fill the tank in 24 minutes and efficiency of pipe – P is 60% more than the efficiency of pipe – D, then find the total capacity of the tank?**

(a) 2000 liters

(b) 2400 liters

(c) 1800 liters

(d) 2500 liters

(e) 3000 liters
