This qn is similar to the type of qn as e following :
A student answers 10 test qns. For every correct answer he gets 4 marks, for every wrong answer 2 marks are deducted...etc.
So use similar method to solve.
Anyway, solution is :
(400-58)/9 = 38. He sold 38 large bowls. Solve accordingly.

Hope the above helps.
