6) Sumkaning narxi 200000 so‘m edi. Avval sumkaning narxi uning \(\frac{1}{5}\) qismicha qimmatlashdi, keyin yangi narx o‘zining \(\frac{1}{4}\) qismicha arzonlashdi. Sumkaning hozirgi narxini toping.

Birinchi qimmatlashishdan keyingi narx: \(200000+200000\cdot\frac{1}{5}=200000+40000=240000\) so‘m.

Arzonlashgan summa: \(240000\cdot\frac{1}{4}=60000\) so‘m.

Hozirgi narx: \(240000-60000=180000\) so‘m.

Javob: 180000 so‘m.
