According to Question :

its cost in next year will be 15% less.

Y = Cost of car in next year .

\large\implies{\sf Y=x-0.15x}

\large\implies{\sf Y=0.85x}

Now , again next year its price will be 15% less.

so ,

\large\implies{\sf Y-0.15Y=0.85x}

We know cost price after 2 years is Rs.2,16,750

\large\implies{\sf  0.85x=216750}

\large\implies{\sf Y=0.85}

\large\implies{\sf 0.85×0.85x=216750}

\large\implies{\sf x=300000 }
