### Instruction:
 Jan ananunua waya wa futi 1000. Anaugawa katika sehemu za futi 25. Anampa rafiki 1/4 ya hizo. Kisha anaweka nusu ya zilizobaki kwenye uhifadhi. Anabakiwa na kiasi gani mkononi?


### Response:
 Anapata sehemu 1000/25=<<1000/25=40>>40.
Anawapa sehemu 40/4=<<40/4=10>>10.
Hivyo, anabakiwa na sehemu 40-10=<<40-10=30>>30.
Anabakiwa na sehemu 30/2=<<30/2=15>>15 mkononi.
