The difference of marks scored by Amit in Chemistry in Test-2 and that in English in Test-1 is
9
To find the difference between the marks scored by Amit in Chemistry in Test-2 and English in Test-1, we calculate the individual marks scored in each:
Marks in English (Test-1):
Total marks in Test-1 = $750$
Percentage in English = $18\%$
$\text{Marks} = \frac{18}{100} \times 750 = 135$
Marks in Chemistry (Test-2):
Total marks in Test-2 = $800$
Percentage in Chemistry = $18.000\%$
$\text{Marks} = \frac{18}{100} \times 800 = 144$
Difference:
$$\text{Difference} = 144 - 135 = 9$$
Correct Answer: Option 3 (9)
