Solution
THIS QUESTION WAS DELETED, BECAUSE THEY DIDN'T MENTION THAT THE TABLE CONSISTS OF PERCENTAGES RATHER THAN THE ACTUAL MARKS OF STUDENTS
To find the overall percentage for each subject, we calculate the average of the percentage scores of all the students for that subject:
Physics: $$\dfrac{70+80+75+60+70+65}{6}=\dfrac{420}{6}=70\%$$
Biology: $$\dfrac{75+70+72+70+75+70}{6}=\dfrac{432}{6}=72\%$$
Maths: $$\dfrac{70+75+71+65+65+60}{6}=\dfrac{406}{6}=67.67\%$$
Geology: $$\dfrac{65+60+70+55+50+65}{6}=\dfrac{365}{6}=60.83\%$$
Economics: $$\dfrac{60+50+60+60+55+50}{6}=\dfrac{335}{6}=55.83\%$$
English: $$\dfrac{70+75+65+70+60+60}{6}=\dfrac{400}{6}=66.63\%$$
Biology has the highest score of 72%.
