Solution

The correct option is D 100%, 0%

We can see that the student obtained 30 in Maths in 2005-06 and 60 in 2006-07 respectively. So, the increase in number will be = 60 - 30 = 30.

The percentage increase will be
= $\frac{30}{30} \times 100$
= 100%

We can see that the marks in Hindi have remained the same over the two years. The student has obtained 60 in Hindi in both years.

So, the percentage increase in marks in Hindi will be 0%.
