Bu masalani hal qilish uchun avval har bir uyning bo'yoq zaxirasini kuzatamiz. Birinchi uydan 230 - 30x quti (x - kunlar soni) qoldi, ikkinchi uyda esa 321 - 39x quti qoldi. Bizda quyidagi tenglama bor: 321 - 39x = 1.5 * (230 - 30x) Endi bu tenglamani yechamiz: 321 - 39x = 345 - 45x Keyin, x ni bir tomonga, raqamlarni boshqa tomonga o'tkazib: 6x = 24 Shunday qilib, x = 4. Demak, 4 kundan keyin ikkinchi uyda ishlatilmagan bo'yoq birinchisidan 1,5 marta ko'p bo'ladi.
