Select an option to attempt

Explanation

P scored 40 marks more than Q. So, marks of Q are $q$ , then the marks of P will be $q + 40$ .

Q scored 10% less marks than P. That is, marks of Q are 90% of the marks of P.

So, $q = 90\%$ of $(q + 40)$

Or $10q = 9q + 360$

Or $q = 360$

So, Q scored 360 marks.
