Explanation:

- Anuj sold the car for Rs.5,54,400 at a 12% loss. This means the selling price represents 88% of Anuj's purchase price.

- Let Anuj’s cost price be $x$.

- From the equation, $0.88x=5,54,400$.

- Solving, $x=5,54,400/0.88=6,30,000$.

- Aman suffered a 10% loss when selling to Anuj. Thus, Anuj’s purchase price of Rs.6,30,000 represents 90% of Aman's purchase price.

- Let Aman’s cost price be $y$.

- From the equation, $0.9y=6,30,000$.

- Solving, $y=6,30,000/0.9=7,00,000$.

- ?? The cost price of the car for Aman is Rs.7,00,000.
