What is the largest positive value that can be represented by an 8 bit 2’s complement number

What is the largest positive value that can be represented by an 8 bit 2’s complement number Correct Answer 127

Two's complement representation, or, in other words, signed notation - the first bit tells about the sign.

The convention is that a number with a leading 1 is negative, while a leading 0 denotes a positive value.

In an 8-bit representation, we can write any number from -128 to 127.

The name comes from the fact that a negative number is a two's complement of a positive one.

In a certain number system there are only two notations to represent numbers: @ and %. 0 is represented by @ and 1 by %. The subsequent numbers are represented in the following manner: 2 is represented as %@, 3 is represented as %%, 4 is represented as %@@, 5 is represented as %@% and so on. Based on this coded language, answer the following questions: What number is represented by %%@%@%%?
A word is represented by only set of numbers as given in any one of the alternatives. The sets of numbers given in the alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are number alternatives are represented by two classes of alphabets as shown in the given two matrices. The columns and rows of Matrix-I are numbered from 0 to 4 and that of Matrix-II are numbered from 5 to 9. A letter from these matrices can be represented first by its row and next by its column, for example ‘A’ can be represented by 10, 75 etc and ‘B’ can be represented by 44, 79 etc. Similarly, you have to identify the set for the word ‘FOLDER’.  Matrix I    Matrix II   0 1 2 3 4   5 6 7 8 9 0 H L F M I 5 E I C J G 1 A U W S E 6 P R U S K 2 R Y C Z O 7 A W O D B 3 K T X V J 8 O T V Q L 4 D Q G P B 9 H N D M F
