Two squirrels, Nutty and Pip, are gathering acorns. Nutty says: 'If you give me one of your acorns, I will have twice as many as you.' Pip replies: 'If you give me one of your acorns, we will have an equal amount.' How many acorns does each squirrel currently have?
Nutty has 7 acorns and Pip has 5 acorns.
If Pip gives 1 acorn to Nutty: Nutty has 7+1=8, Pip has 5-1=4 (8 is twice 4). If Nutty gives 1 acorn to Pip: Nutty has 7-1=6, Pip has 5+1=6 (equal amounts).
