Answer 1

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 :

$\mathsf{\implies \frac{30}{10}}$

$\mathsf{\implies 3 : 1}$  (1st Blank)

The Ratio of the Number of Correct Answers to Total Number of Questions is :

$\mathsf{\implies \frac{30}{40}}$

$\mathsf{\implies 3 : 4}$

If there is 100 Questions on the test and the Ratio stayed the same, The Number of Questions he would have answered correctly is :

$\mathsf{\implies \frac{3}{4} \times Total\;Number\;of\;Questions}$

$\mathsf{\implies \frac{3}{4} \times 100}$

$\mathsf{\implies (3 \times 25)}$

$\mathsf{\implies 75}$  (2nd Blank)
