Answer 2

Answer:

65%

Step-by-step explanation:

Let the marks in third paper be x%

Ranjan got 45%marks in first paper

Ranjan got 70%marks in second paper

He got  60% as overall score.

Overall score is average of 3 scores

So, $60=\frac{45+70+x}{3}$

$180=45+70+x$

$180=115+x$

$180-115=x$

$65=x$

So, he should get 65% marks in third paper .
