The number of croissants that Ahmad had remains unchanged.
If Ahmad had another 12 croissants in the end, the number of croissants that Raeann and Ahmad had would be the same.
4 u - 3 = 1 u + 12
4 u - 1 u = 12 + 3
3 u = 15
1 u = 15 ÷ 3 = 5
Total number of croissants
= 4 u + 1 u
= 5 u
= 5 x 5
= 25
Answer(s): 25
