Explanation
To find the market price of the car without tax, we need to remove the 6% sales tax from the total price of Rs. 154,431.40.
Let the market price of the car be P.
Including 6% sales tax, the equation is:
P + 0.06P = 154,431.40
1.06P = 154,431.40
Now, solve for P:
P = 154,431.40/1.06
P = 145,690
So, the market price of the car without tax is Rs. 145,690.
