Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Exactly two-fifths of NBA players who signed up for a test are aged between 25 and 35 years. If three-eighths of them are older than 35, and a total of 1000 players signed up, how many players are younger than 25 years?

### Response:
 Wachezaji wawili wa tano wa 1000 ni (2/5)*1000 = <<2/5*1000=400>>400 wachezaji
Wachezaji watatu wa nane wa 1000 ni (3/8)*1000 = <<3/8*1000=375>>375 wachezaji
Jumla ya wachezaji wenye umri wa miaka 25 au zaidi ni 400+375 = <<400+375=775>>775 wachezaji
Idadi ya wachezaji wenye umri chini ya miaka 25 ni 1000-775 = <<1000-775=225>>225 wachezaji
