1. Answer:

   If the money is to grow 4 fold, then assuming amount invested as Rs.100/- interest earned should be Rs.300/ and the total sum will be Rs.400/

   On Rs.100/ interest earned per year Rs.10/-

   Interest earned for 30 years is Rs.300/-

   So, it will take 30 years the money will become 4 folds at 10% simple interest.
