Answer 1

15 fete................10 baieti......................420 panselute
12 fete.................10 baieti....................360 panselute

15-12=3 fete
420-360=60 panselute (3 fete)
60:3=20 panselute (o fata)

15x20=300panselute (15 fete)
420-300=120 panselute (10 baieti)
120:10=12 panselute (un baiat)

Answer 2

15fete+10baieti=420
12fete+10baieti=360
3fete=60flori
1fata=20flori
15×20+10baieti=420
10baieti=420-300=120
1baiat=12flori
