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.
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
Directions (11-15):- Given bar graph shows the details of number of students in a particular class of 3 different schools in 5 different years.
Q11.What is the difference between average number of students of school A across all the years and the average number of students of school B across all the years?
Q12.Find the respective ratio of the total number of students of school A in 2011 and 2012 together to the total number of students of school C in 2013 and 2014 together?
Q13.If in 2016, the total number of students in School A, School B and School C increases by 10%,20% and 15% respectively as compared to 2015, then find the total number of students in 2016 in all the schools together?
Q14.Total students of all the school together in 2013 is approximately what percentage more/less than the total students of school B in 2011 and 2015 together?
Q15.Find the difference between the number of total students from all the schools in 2011 and 2013 together and the total number of students from all the schools in 2014 and 2015 together?
