Important tips to solve Table Chart

Introduction

Table chart is simplest method used for data. In a table, data is arranged systematically in columns and rows. The first row and the first column are generally used to indicate the titles. It is one of the easiest and most accurate way of presenting the data.

Important Points

1. Read the data very carefully and try to understand what you are being asked to do. To prevent wasting time in calculation and find out what is required.

2. Check the data and information carefully before jumping to answer the questions. Be sure you are looking at the right part of column and tables.

3. Carefully check the units, Be sure you are taking same unit as you have given like in thousand, millions etc. A mistake in units and your answer may be different.

Sample Question

Direction: Refer to the following table and answer the given questions.

Number of cars sold by 6 Stores in 5 different months

The above Table shows:

• The number of cars sold by store P (In Jan = 133, Feb = 183, March = 278, April = 178, May = 264)

Like this we can see the others. Lets do solve some questions.
1. Number of cars sold by store T in march is what percent less then number of cars sold by Store P in may? (Rounded off to nearest integer)
(a) 29%
(b) 31%
(c) 37%
(d) 33%
Solution:
Number of  cars sold by Store T in March = 178
Number of cars sold by store P in May = 264
Required percentage = (264 - 178 /264) * 100 (in question asked less then number that’s why we deducted) = (86/264) * 100 = 32.57%
So rounded figure it will be 33%, Answer D
2. What is the average number of cars sold by all the given stores in Feb?
(a) 207
(b) 211
(c) 219
(d) 223
Solution:
To find average we have to add all the figures of Feb month and then divided by 6
= 183 + 123 + 277 + 176 + 239 + 268 / 6 = 1266/6 = 211, Answer B
3. Total number of cars sold by store Q during  all the given months together is what percent of the total number of cars sold by store S during all the given month together?
(a) 82%
(b) 88%
(c)92%
(d) 86%
Solution:Total number of cars sold by store Q during  all the given months together = 161 + 123 + 154 + 272 + 107 = 817
Total number of cars sold by store S during  all the given months together = 225 + 176 + 98 + 284 + 167 = 950
Required percentage = (817/950) * 100= 86%, Answer D
4. What is the difference between total number of cars sold by all the given stores together in Jan and total number of cars sold by all the given stores together in April?
(a) 353
(b) 379
(c) 363
(d) 347
Solution:
Total number of cars sold by all the given stores together in Jan = 133 + 161 + 213 + 225 + 282 + 196 = 1210
Total number of cars sold by all the given stores together in April = 178 + 272 + 269 + 284 + 293 + 277 = 1573
Required difference = 1573 - 1210 = 363, Answer C
5. What is the respective ratio between total number of cars sold by stores P and R together in March and total number of cars sold by stores T and U together in May?
(a) 9:11
(b) 11:13
(c) 5:7
(d) 13:17
Solution:
Total number of cars sold by stores P and R together in March = 278 + 226 = 504
Total number of cars sold by stores T and U together in May = 379 + 237 = 616
Ratio= 504 : 616 = 9 : 11, Answer A
