Study the following mixed graph carefully and answer the questions that follow.

The graph illustrates the number of electric cars manufactured by a company over five years and the percentage exported each year. Cars not exported were sold within the country.

Year	Cars manufactured (in thousands)	Exported
2020	80	25%
2021	100	30%
2022	120	35%
2023	150	40%
2024	180	45%

The company earned an average profit of ₹1,50,000 on each exported car and ₹80,000 on each car sold within the country. What is the percentage increase in the difference between export profit and domestic profit (in ₹ crore) in 2024 compared to 2023 if the profit margins remained the same?

35%

42.55%

74.07%

135%

2023	150,000	60,000	90,000
2024	180,000	81,000	99,000

For 2023, export profit $=60,000\times₹1,50,000=₹900$ crore and domestic profit $=90,000\times₹80,000=₹720$ crore. The difference is $₹180$ crore.

For 2024, export profit $=81,000\times₹1,50,000=₹1,215$ crore and domestic profit $=99,000\times₹80,000=₹792$ crore. The difference is $₹423$ crore.

Percentage increase $=\dfrac{423-180}{180}\times100=135\%$ .
