Question

In a tally mark, a group of eight marks is represented as:

Answer 1

Hint:Here we check each given option separately. Using the knowledge of tally marks that after every four vertical lines the fifth line is a diagonal line to the four lines.
* Tally mark is an easy way to keep track of counting in packs of five.
* Tally marks is also called hash marks

Complete step-by-step answer:
We have to find a representation of a group of eight marks.
First we break the mark which we have to represent in a tally mark.
\[8 = 5 + 3\]
Therefore, we make one complete group of five vertical lines and one group having three vertical lines.
So, we draw four vertical lines and then cut the group of four vertical lines by a diagonal which forms one collection and the second collection has three vertical lines.
So, we represent \[8\] In terms of tally marks as

     \[5\] \[ + \] \[3\] \[ = 8\]
Therefore, option A is correct.
Checking options B, C, D they all have a first collection with five vertical lines which is incorrect because the fifth line is supposed to be diagonal. Therefore all other options other than A cancel out.

Note:Students can opt for drawing the diagonal line from any direction be it left top to right bottom or right top to left bottom. Tally marks is used for keeping scores in a game, used in frequency tables etc. Always note that tally marks is never used for counting of large numbers as it is very time consuming and students might have to revisit calculations all over again if they commit one single mistake.
Alternate method:
Alternate way to represent \[8\] In terms of tally marks is
                    

     \[5\] \[ + \] \[3\] \[ = 8\]
Therefore, option A is correct.
