| Question 3 |
In a dot matrix printer to print a character is 6 m.sec., time to space in between characters is 2 m.sec., and the number of characters in a line are 200. The printing speed of the dot matrix printer in characters per second and the time to print a character line are given by which of the following options ?
| 125 chars/second and 0.8 seconds | |
| 250 chars/second and 0.6 seconds | |
| 166 chars/second and 0.8 seconds | |
| 250 chars/second and 0.4 seconds | |
| None of the above |
Question 3 Explanation:
If we have 3 characters then the space between two characters will be 2. It means if we have “n” characters in a line then the number of spaces in the line will be “(n-1)”.
So, the time to print a character line = (200*6)+(199*2)
= 1598 ms
= 1598*10-3 second
= 1.59 seconds
Printing speed of the dot matrix printer in characters per second
= 200/ 1.59 character per second
= 125.78 character per second
So, the time to print a character line = (200*6)+(199*2)
= 1598 ms
= 1598*10-3 second
= 1.59 seconds
Printing speed of the dot matrix printer in characters per second
= 200/ 1.59 character per second
= 125.78 character per second
Correct Answer: E
