A car dealer purchased an old car for Rs.1,08,500 and spent some amount on its maintenance. He sold it for Rs.1,56,250, there by earning a profit of 25%. How much money did he spend on the maintenance of the car?

Rs. 16,500

CP of the car = 1,08,500

Let the amount spent on car maintenance = m

SP of the car = 156250

Price of the car after maintenance = 1,56250 × \(\frac{100}{125}\)  = 1,25,000

m = 125000 - 108500

= m = 16500
