Explanation :
Anything larger and the computer would need to break the number into smaller pieces. 16-bit is a computer hardware device or software program capable of transferring 16 bits of data at a time. Today, 16-bit hardware and software has been replaced by 32-bit and 64-bit alternatives, which give the computer more memory to work with; increasing overall performance. For example, early computer processors (e.g., 8088 and 80286) were 16-bit processors, meaning they were capable of working with 16-bit binary numbers (decimal number up to 65,535).

Answer : 3. "Any two of (1, 2 & 3)"
Explanation :
Answer: C) Any two of (1, 2 & 3) Explanation: Using Both 1 & 2 statements we get the rate of interest as in (1) we have given principle amount and in (2) compound interest for 2 years. By this data we get the rate%. Using Both 1 & 3 statements we can get the rate% as we have principle amount & difference between compound interest and simple interest in 2 years. Using Both 2 & 3 statements we get compound interest & simple interest by which we get principle amount. So that we can calculate %rate. Hence by using any two of the three statements(1,2&3) we get rate of interest.
