Given : The Number of Correct Answers = 30
Given : Total Number of Questions = 40
⇒ The Number of Wrong Answers = (40 - 30) = 10
The Ratio of the Number of Correct Answers to Number of Wrong Answers is :
[tex]\mathsf{\implies \frac{30}{10}}[/tex]
[tex]\mathsf{\implies 3 : 1}[/tex] (1st Blank)
The Ratio of the Number of Correct Answers to Total Number of Questions is :
[tex]\mathsf{\implies \frac{30}{40}}[/tex]
[tex]\mathsf{\implies 3 : 4}[/tex]
If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :
[tex]\mathsf{\implies \frac{3}{4} \times Total\;Number\;of\;Questions}[/tex]
[tex]\mathsf{\implies \frac{3}{4} \times 100}[/tex]
[tex]\mathsf{\implies (3 \times 25)}[/tex]
[tex]\mathsf{\implies 75}[/tex] (2nd Blank)
