He averages 40 in 5 matches, hence his score all-up is 5 x 40 = 200.

His lowest score is 24, hence we are looking for such that

Solving the equation we get:





Hence the highest possible value for his second lowest score is 44 - 1 = 43.

Hope this is right. :p

I don't think it is right, because it says 5 different scores... if his second lowest was 43, he'd need two 44s and a 45 to average 200.

Yep, it does work, but it's not as high as the second lowest score can go. :p
