Question

The total number of ways of answering 5 objective-type questions, each question with four choices is:

• A. 64
• B. 125
• C. 625
• D. 1024

Answer 1

The correct option is D 1024

An answer can be chosen from the given 4 options in ${}^4{C}_1$ ways = 4 ways.
Similarly, for all the 5 questions, there are 4 ways each.
Hence, the total number of ways of answering 5 questions $=4\times 4\times 4\times 4\times 4=1024$ ways
