Financial talk

My Mother has presently Fixed deposits in UTI and other banks. Being Senior Citizen she gets 10% on FD. If She puts money In Savings she will get a 3.5% Rate of Interest. There is a scheme from Hongkong bank where You have to invest with them for 3 yrs and based on the BSE Sensex they will give you the return. If the Sensex falls below the value you had invested at that time ..you are still assured of 9.5% return. Question : Which is the best place to invest where the money is safe and one earns also. UTI though gives 10% rate of interest but then 30% is deducted for TDS. Is HSBC Scheme better than others or are there other place where we can invest where money is safe and returns are higher ( avoiding mutual funds , stock markets etc)
