5. Jamshidning puli Alishernikidan 3 barobar ko‘p. Rahimning puli Alishernikidan 2400 so‘mga ortiq. Uchta bolada jami 27 400 so‘m pul bor. Har bir bolada qanchadan pul bor?

Alisherning pulini \(x\) so‘m deb olamiz.

Jamshidda: \(3x\) so‘m.

Rahimda: \(x+2400\) so‘m.

Jami pul bo‘yicha tenglama tuzamiz:

\(x+3x+(x+2400)=27400\).

\(5x+2400=27400\),
\(5x=25000\),
\(x=5000\).

Alisherda 5000 so‘m, Jamshidda \(3\cdot5000=15000\) so‘m, Rahimda \(5000+2400=7400\) so‘m.

Javob: Alisherda 5000 so‘m, Jamshidda 15 000 so‘m, Rahimda 7400 so‘m bor.
