Study the following pie chart and answer the question:
Distribution (degree wise) of the number of mobile phones sold by a dealer during January to May 2022.
Total number of mobile phone sold during these five months = 1800
The dealer earned a profit of ₹ 1200 per mobile phone during January and March. The profit per mobile phone was ₹ 1000 during April and May. What was the difference (in ₹) between the total profit earned by the dealer in January and March and the total profit earned in April and May?
Answer: C
The difference is 28800 rupees. The sales in each month follow from the angles of the pie chart, out of 360 degrees and 1800 phones, so each degree stands for 5 phones. January: 82.8 x 5 = 414. March: 50.4 x 5 = 252. April: 73.8 x 5 = 369. May: 91.8 x 5 = 459. January and March: (414 + 252) x 1200 = 666 x 1200 = 799200. April and May: (369 + 459) x 1000 = 828 x 1000 = 828000. The difference is 828000 - 799200 = 28800. February is not used in the question, and options such as 28200 and 28400 do not match this calculation.
