If Mukesh got $80 \%$ on a test which has a total of 50 marks, how many marks did he get?
(A) 40
(B) 62.5
(C) 10
(D) 45
(E) 35
Solution 1

As a fraction, $80 \%$ is $\frac{80}{100}$ or $\frac{4}{5}$.

Therefore, Mukesh got $\frac{4}{5}$ of the possible 50 marks, or $\frac{4}{5} \times 50=40$ marks.

Solution 2

Since Mukesh got $80 \%$ of the 50 marks, he got $\frac{80}{100} \times 50=\frac{80}{2}=40$ marks.
