Hi,
Here are my two cents for this question
If Paul would have scored 14 more marks than A on third test their averages would be same .
Additionally, We know that if we add or subtract each term by a constant than average will increase or decrease by that constant.
We can't add 3 to first test and we can't add 3 to second test of paul. This means we need to add 9 to third test of paul apart from scoring 14 points more than A on third test.
So 14+9=23
Was i able to explain this correctly?
