Question

The following data shows the performance of a particular student in 4 subjects viz. Physics, Chemistry, Maths and Biology across 5 different tests. The number in the bracket indicates the maximum marks the student can score in a particular subject.
$\begin{array}{cccccc}Subject& Physics\left(25\right)& Chemistry\left(25\right)& Maths\left(30\right)& Biology\left(20\right)& Total\left(100\right)\\ Test1& 16& & 20& & \\ Test2& 14& 19& 23& & \\ Test3& & 20& & & 75\\ Test4& & & & 15& 74\\ Test5& & & 24& 16& 72\\ & & & & & 360\end{array}$

The following chart shows the distribution of total marks scored in a particular subject as a percentage of total marks scored in all tests.
