Question

Rory has 25 lollies that he shares with 3 other friends.

He gave Steve 2 more than he kept for himself.

He gave Delilah 3 less that lollies of Steve.

Kelly has twice as many as Steve.

How many lollies did Rory keep for himself?

Worked Solution

By trial and error:
If R = 1, S = 3, D = 0, K = 6 (10 total)
R = 2, S = 4, D = 1, K = 8 (15 total)
R = 3, S = 5, D = 2, K = 10 (20 total)
R = 4, S = 6, D = 3, K = 12 (25 total)

∴\therefore Rory kept {{{correctAnswer0}}} lollies.
