Answer 2

Answer:

He needs to score $61.5$% marks in political science.

Step-by-step explanation:

It is given that Paul scored $75$% in English and $84$% in Mathematics.

We need to determine minimum percent he should score in Political Science if he aims at scoring $75$% overall.

Also English and Mathematics are for $150$ marks each and Political Science is for $100$.

If marks are $150$, then marks obtained in English $=0.75*150=112.5$

If marks are $150$, then marks obtained in English $=0.84*150=126$

Let marks in Political Science be $x$.

Total marks in political science is $100$.

Total  Maximum marks $=150+150+100=400$

Overall $75$% means $0.75*400=300$

Hence, $112.5+126+x=300$

$x=61.5$

Hence, he needs to score $61.5$% marks.
