Botir va Alisher o'rtasidagi pul nisbatini $5x$ va $9x$ deb olaylik. Ularning jami to'plagan pullari $5x + 9x = 14x$ ga teng. To'plangan pul 28000 so'm, shuning uchun: \[ 14x = 28000 \] $ x $ ni topish uchun ikkala tomonni 14 ga bo'lamiz: \[ x = \frac{28000}{14} = 2000 \] Botirning hissasi $5x$ ga teng bo'ladi: \[ 5x = 5 \times 2000 = 10000 \] Shunday qilib, Botir sovg'aga 10000 so'm qo'shgan.
