1. Which of the following is the binary equivalent of the decimal number 186?
A. 10100110
[COLOR=”DarkOrange”]B. 10111010 [COLOR=”Magenta”]Correct!
C. 11000010
D. 10101100
Question 1 of 3 Questions total.
Number of Tries 0
Number of Correct Answers 0
My problem is that I want the correct answer (? is to be in red color when I click on it, and others will be in light blue or fade or blur, so that the user will be able to see only the correct answer more clearer than any other answers.
And if the correct answer was clicked, means that user has chose the correct answer for that question, then those A, B, C or D answer will not allow to click again.
How can I get the grade, such as if user got the right answer for each question, then he will earn 1%, 2% and so on until he got 100% if he got all 100 questions.
