Answer 2

Student a performed better.

Step-by-step explanation:

Since we have given that

Number of marks student a scored out of 30 = 20

So, percentage becomes,

$\dfrac{20}{30}\times 100\\\\=66.66\%$

Number of marks student b scored out of 70 = 40

So, percentage becomes,

$\dfrac{40}{70}\times 100\\\\=57.14\%$

Hence, Student a performed better.
