Introduction: The questions on table charts in the State Bank of India (SBI) Probationary Officers exams have been asked frequently. After the study of the previous year question papers we can say the data interpretation section will consist of 2 β 3 table charts with 10 β 15 questions. It is advisable to every student to understand the concept of table chart so that they can earn good marks in the section.
Table Charts: These are the charts of facts and figures shown in horizontal rows and vertical columns. A table chart can contain facts and figures related to cities, states, countries, time periods, individual names, companies and miscellaneous information.
The questions on the basis of the table charts are generally asked to find the relation among the facts and the figures. The question can be asked to find average, ratio or percentage of some facts and figures related to some other facts and figures.

In studying problems on statistics, the data collected by the investigator are arranged in systematic form, called the tabular form. In order to avoid some heads again and again, we make tables, consisting of horizontal lines called rows and vertical lines called columns with distinctive heads, known as captions. Units of measurements are given along with the captions.
Example:
The table given below shows the population, literates and illiterates (in thousands) and the percentage of literacy in 3 states, in a year:
State Population Literates Illiterates Percentage of
literacy
Madras 49342 6421 β¦β¦β¦.. β¦β¦β¦
Bombay β¦β¦β¦. 4068 16790 β¦β¦β¦..
Bengal 60314 β¦β¦β¦ β¦β¦β¦ 16.1
After reading the table, mark a tick (β) against the correct answer in each question given below and hence complete the table.
6. Percentage of literacy in Madras is
(a) 14.9% (b) 13.01% (c) 12.61% (d) 15.04%
7. Percentage of literacy in Bombay is
(a) 19.5% (b) 16.7% (c) 18.3% (d) 14.6%
8. Number of literates in Bengal(in thousands) is:
(a) 50599 (b) 9715 (c) 76865 (d) 9475 Solution:
6. (b) percentage of literacy in Madras = (6421/49342)Γ100% = 13.01%
7. (a) Population of Bombay = (4068+16790) thousands = 20858 thousands.
Therefore, percentage of literacy in Bombay = (4068/20858)Γ100% = 19.5%
8. (b) Number of literates in Bengal =(16.1/100)Γ60314 = 9715 thousands
