Sebastian has 5 boxes of sweets on Monday. Each box has 4 sweets in it. He divides all his sweets into 10 groups, and eats 1 group on Tuesday. He then eats another 2 groups of sweets on Wednesday. How many sweets does Sebastian have left?

Answer:
14 sweets
Step-by-step explanation:
Number of sweets at first = 5 X 4 = 20 sweets
Number of sweets in each group = 20 / 10 = 2 sweets
Tuesday: Sebastian eats 2 sweets
Wednesday: Sebastian ate (2 X 2) 4 sweets
20 - 2 - 4 = 14 sweets
