Table Chart is the simplest form of presenting the data and most widely used in Data Interpretation section of various competitive exams.
Let's have a look at some solved questions based on Table Chart:
Q1. The following table gives the percentage distribution of the population of five states, P, Q, R, S, and T, on the basis of the poverty line and also on the basis of sex.
(i) If the male population above the poverty line for State R is 1.9 million, then the total population of State R is?
(a) 4.5 million
(b) 4.85 million
(c) 5.35 million
(d) 6.25 million
Ans: (d) 6.25 million
Solution: Let the total population of State R be x million.
Then, the population of State R above the poverty line:
And so, the male population of State R above the poverty line:
But, It is given that the male population of State R above poverty line = 1.9 million
∴ The total population of State R = 6.25 million
(ii) What will be the number of females above the poverty line in State S if it is known that the population of State S is 7 million?
(a) 3 million
(b) 2.43 million
(c) 1.33 million
(d) 5.7 million
Ans: (b) 2.43 million
Solution: Total population of State S = 7 million.
∴ Population above poverty line = {100  19}% of 71 million = 81% of 7 million = 5.67 million.
And so, the number of females above the poverty line in State S:

Ans: (b) 10:13
Solution:
Q3. Read the table given below and answer the questions accordingly.
Shares traded on Bangalore, Madras, Bombay Stock Exchanges (in Rupees)
(i) The average of the high rates of share in all the three Stock Exchanges for NEPC Tea is
(a) Rs.28.422.
(b) Rs.27.423.
(c) Rs.29.14.
(d) Rs.28.93
Ans: (a) Rs.28.422.
Solution: The last column is the total of all three stock exchanges (high rates and low rates, resp.) for every company. So, the average for NEPC high rates = 85.25/3= Rs. 28.42. Hence, the answer is 1st option.
(ii) For Reliance, the low rate of share is less than the average of the low rates of shares of the same company, in the Stock Exchange at
(a) Madras
(b) Bombay
(c) Bangalore
(d) None of these
Ans: (c) Bangalore
Solution: Average of low rates of shares of Reliance = (177.5+177.5+177)/3> 177, which is the low rate of share of Reliance at Bangalore stock exchange. So, the correct option is 3.
(iii) For Tata Steel, the ratio of the high rate of share to the low rate is maximum in the Stock Exchange at
(a) Bangalore
(b) Madras
(c) Bombay
(d) None of these
Ans: (c) Bombay
Solution: At Bangalore Stock Exchange, ratio of high rate to low rate = (160/143) = 1.11;
At Madras Stock Exchange, ratio of high rate to low rate = (158/140.5) = 1.12;
At Bombay Stock Exchange, ratio of high rate to low rate = (161.25/142.5) = 1.13.
As the maximum ratio is in Bombay, it will be the answer. Hence, the answer option is 3.
(iv) The low rate of share in L & T at Madras Stock Exchange bears a ratio, to the total low rate of share of the same company, of
(a) 8/19

Solution: Low rate of share of L & T at Madras Stock Exchange = Rs. 180.
Total of low rate of share of L & T in all three Stock Exchanges = Rs. 500.
Ratio of (i)/(ii)= 180/500 = 9/25. Hence, the answer is 4th option.

(ii) What was the total number of Peons working in the Company in the year 1999?
