Prime Shopper: Lower Secondary Mathematics Competition Question


Marcus is trying to carry three bags of shopping. Each bag weighs a prime number of kg and the total weight is 25 kg. However, one of the bags is far too heavy for him. He would like to redistribute the items in the bags in such a way that his left and right arms are carrying nearly the same weight and he still has three prime number weights.

How much does each bag weigh? And how much did each bag weigh before Marcus redistributed the items?
