Ques 5 : Choose the correct answer
Rajni wants to create a data-type for the number of books in her book case. Her shelf can accommodate a maximum of 75 books. She allocates 7 bits to the data-type. Later another shelf is added to her book-case. She realizes that she can still use the same data-type for storing the number of books in her book-case. What is the maximum possible capacity of her new added shelf?
Option 1 : 52	Option 2 : 127	Option 3 : 53	Option 4 : 75
Ques 6 : Choose the correct answer
A new language has 15 possible letters, 8 different kinds of punctuation marks and a blank character. Rahul wants to create two data types, first one which could store the letters of the language and a second one which could store any character in the language. The number of bits required to store these two data-types will respectively be:
Option 1 : 3 and 4	Option 2 : 4 and 3	Option 3 : 4 and 5	Option 4 : 3 and 5
Ques 7 : Choose the correct answer
Parul takes as input two numbers: a and b. a and b can take integer values between 0 and 255. She stores a, b and c as 1-byte data type. She writes the following code statement to process a and b and put the result in c. c = a + 2*b To her surprise her program gives the right output with some input values of a and b, while gives an erroneous answer for others. For which of the following inputs will it give a wrong answer?
Option 1 : a = 10 b = 200	Option 2 : a = 200 b = 10	Option 3 : a = 50 b = 100	Option 4 : a = 100 b = 50
Ques 8 : Choose the correct answer
Prashant takes as input 2 integer numbers, a and b, whose value can be between 0 and 127. He stores them as 7 bit numbers. He writes the following code to process these numbers to produce a third number c. c = a - b In how many minimum bits should Prashant store c?
Option 1 : 6 bits	Option 2 : 7 bits	Option 3 : 8 bits	Option 4 : 9 bits
Ques 9 : Choose the correct answer
Ankita takes as input 2 integer numbers, a and b, whose value can be between 0 and 31. He stores them as 5 bit numbers. He writes the following code to process these numbers to produce a third number c. c = 2*(a - b) In how many minimum bits should Ankita store c?
Option 1 : 6 bits	Option 2 : 7 bits	Option 3 : 8 bits	Option 4 : 9 bits
Ques 10 : Choose the correct answer
A character in new programming language is stored in 2 bytes. A string is represented as an array of characters. A word is stored as a string. Each byte in the memory has an address.
