A man buys a truck for Rs. 2,50,000. The annual repair cost comes to 2% of the price of purchase. Besides, he has to pay an annual tax of Rs. 2000. At what monthly rent must he rent out the truck to get a return of 15% on his net invests of the first year?

Explanation:-

The total cost for the year = 250000+2% of 2500000+2000 = Rs. 257000.
For getting return of 15% he must earn = 257000*15/100 = Rs. 38550 per year.
Then, monthly rent = 38550/12 = Rs. 3212.5.
