Rohit took a loan of Rs. 30,000 from Rajesh. The condition of Rajesh set for Rohit was that for the first four years the rate of interest would be at 10% simple interest per years and at 20% compound interest compounded annually from the fifth years onwards. Rohit payed foul and did not pay anything until the end of sixth year. How much would he have to repay if he is to clear the entire amount only at the end of the sixth years (in Rs. )?
