exams was 25, then according to Ram's
target, how much should have been his
total score.​

Answer 1

$\huge\green{ANSWER:-}$

✬ let there are x no. of subjects

so in quarterly exam RAM gets total (80-3)*x=77x

and in half yearly exam RAM gets total (80+2)*x=82x

☞therefore 82x-77x=25

or,5x=25

so x=5

Total marks aimed by ram is 80*5=400
