Question : The following bar graph shows the total number of newspaper readers (in thousands) in a city during 6 consecutive months in a particular year and the respective percentages of the above-mentioned readers who read Hindi newspapers. The rest of the readers read English newspapers.
Note: Total readers = Hindi newspaper readers + English newspaper readers
What is the difference between the number of Hindi newspaper readers during January, February, and April taken together and that of English newspaper readers during March, May, and June taken together?
Option 1: 154500
Option 2: 114500
Option 3: 176500
Option 4: 138700
Correct Answer: 114500
Solution :
Total Hindi newspaper readers during January, February, and April taken together = $\frac{65}{100}×140+\frac{70}{100}×150+\frac{90}{100}×75$
= 91 + 105 + 67.5
= 263.5 thousand
Total English newspaper readers during March, May, and June taken together = $\frac{60}{100}×130+\frac{50}{100}×110+\frac{20}{100} × 80$
= 6 × 13 + 5 × 11 + 2 × 8
= 78 + 55 + 16
= 149 thousand
The difference between the number of Hindi newspaper readers during January, February, and April taken together and that of English newspaper readers during March, May, and June taken together = [263.5 – 149 ] × 1000
= 114.5 × 1000
= 114500
Hence, the correct answer is 114500.
