Find the gain percent on the sale of a car whose cost price is Rs.2.2 million, cost of repairs is Rs.2,00,000 and its selling price is Rs.3 million.

Correct option is D

1. Calculate the total cost price:
· Cost price of the car = Rs. 2,200,000
· Cost of repairs = Rs. 200,000
· Total cost price = Rs. 2,200,000 + Rs. 200,000 = Rs. 2,400,000
2. Calculate the profit (gain):
· Selling price = Rs. 3,000,000
· Profit = Selling price - Total cost price
· Profit = Rs. 3,000,000 - Rs. 2,400,000 = Rs. 600,000
3. Calculate the gain percent:
· Gain percent = (Profit / Total cost price) x 100
· Gain percent = (600,000 / 2,400,000) x 100
· Gain percent = (1/4) x 100 = 25%
Therefore, the gain percent on the sale of the car is 25%.
