Question

In a class test, Dinesh got 12 marks out of 20 in science and 20 marks out of 30 in Maths. In which of the two subjects is his performance better?

Answer 1

Hint: - Here we go through by finding the percentage score in the physics or math’s by the rule of finding the percentage to compare in which subject his performance is better.

Complete step-by-step solution -
Here in the question it is given that,
Marks scored by Dinesh in science out of 20=12
Now we have to find the percentage that Dinesh secured in science.
% marks in science=\[\dfrac{{12}}{{20}} \times 100 = 60\% \]
Marks scored by Dinesh in Math’s out of 30 = 20
Similarly we have to find the percentage that Dinesh secured in math.
% marks in math=\[\dfrac{{20}}{{30}} \times 100 = 66.67\% \]
Here we clearly see that the percentage score in mathematics is greater than the percentage score in science so we can say that Dinesh performance is better in math.

Note: - Whenever we face such a type of question the key concept for solving the question is we cannot compare the marks if the total marks are different for different subjects. So we must need to calculate the percentage to identify in which subject his performance is better.
