Hello Aspirants, As we all know that Data Interpretation is a vital part of quantitative aptitude section for every competitive exams. Data Interpretation is the process of making sense out of a collection of data that has been processed. This collection of data present in the form of charts.(Like – Tabular Chart, Bar Chart, Pie Chart, Line Chart, Missing Data Chart, Caselet Chart and Radar Chart).So here, In this article we will provide different charts with some questions.These Data Interpretation Questions are important for Bank, SSC, SEBI, NABARD, RBI, LIC, and Other state exams. You can attempt these questions & boost your preparation for your examination.
In the Banking exams Data Interpretation Questions asked in the Prelims as well as Mains exam.There are 3-4 Data Interpretation asked in the mains exam (Bank).You want to score more in the Data Interpretation section then you should practice more and more Data Interpretations questions.
This “Data Interpretation Questions and Answers” is also important for other banking exams such as SBI PO, IBPS PO, IBPS Clerk, SBI Clerk, IBPS RRB Officer, IBPS RRB Office Assistant, IBPS SO, SBI SO and other competitive exams.
Data Interpretation Questions Quiz-13
Directions:(1-5) Answer the questions based on the information given below.
The bar graph below provides the information about the number of hours taken by pipes P, Q, R, S and T to empty pool M and pool N while working individually.
1.Pipes Q, R and S are opened alternately for an hour with pipe Q starting first and then pipe R and then pipe S. If they continue being opened in this pattern, then in how many hours would pool N be completely empty?
Portion of pool N emptied in 1st 3 hours = 1/45 + 1/50 + 1/80 = (80 + 72 + 45)/3600 = 197/3600
So, portion of pool N emptied in 1st 54 hours = 18 × (197/3600) = 3546/3600
Portion of pool N remaining to be emptied = 1 – (3546/3600) = 54/3600 = 3/200
Time taken by Pipe Q alone to empty the remaining portion of pool N = (3/200)/(1/45) = 27/40 hours
So, total number of hours taken to empty pool N = 54 + (27/40) = 2187/40 hours
2.If pipes P and Q, both work at half of their original efficiencies and pipe R works at twice its original efficiency, then in how many hours would pool M be completely emptied on opening pipes P, Q and R together?
Portion of pool M emptied by pipe R and T together in one hour = 1/30 + 1/10 = 4/30 = 2/15
So, time taken by pipe R and T together to empty the pool M = 1/ (2/15) = 15/2 hours
Portion of pool N emptied by pipe R and T together in one hour = 1/50 + 1/40 = 9/200
So, time taken by pipe R and T together to empty the pool N = 1/ (9/200) = 200/9 hours
Required difference = 200/9 – 15/2 = 265/18 hours
4.Find the ratio of the number of hours taken by pipe S and T together to empty pool N to the number of hours taken by pipe Q and S together to empty pool M.
Number of hours taken by pipe S and T together to empty pool N = 1/(1/80 + 1/40) = 1/(3/80) 80/3 hours
Number of hours taken by pipe Q and S together to empty pool M = 1/(1/25 + 1/25) = 1/(2/25) = 25/2 hours
Required ratio = 80/3: 25/2 = 32: 15
5.If pipes P, Q, R and S are working together to empty pool M and pipes Q, R, S and T are working together to empty pool N, then what is the difference between the fraction of pool M and the fraction of pool N emptied in 3 hours?

The table below provides the information about 5 different cylindrical tanks (P, Q, R, S and T) and each tank is full, filled with the mixture of oil and water. The table shows the radius and height of each tank and the percentage of oil in each tank with respect to the maximum volume of that tank.

6.What is the ratio of the quantity of oil in tank Q to the quantity of oil in tank S?
8.If 15% of the mixture is taken out from each of the tanks R and T, then find the total amount of water taken out from both the tanks. [Note: 1m3 = 1000 litres]
