Birinchi qopda 30 kg, ikkinchi qopda esa x kg shakar bor. Ikkinchi qop massasi, birinchi va ikkinchi qop massalarining o'rtachasidan 3 barobar kam bo'lsa, ularning massalari yig'indisini toping.
36 kg
30 kg
25 kg

📝 Detailed explanation
Ikki qopdagi shakarning o'rtacha massasi (30 + x) ÷ 2 ga teng. Shartga ko'ra, ikkinchi qopning massasi (x) shu o'rtacha qiymatdan 3 marta kam: x = ((30 + x) ÷ 2) ÷ 3 ⇒ x = (30 + x) ÷ 6. Tenglamani yechamiz: 6x = 30 + x ⇒ 5x = 30 ⇒ x = 6 kg (ikkinchi qop). Qoplarning jami massasi: 30 + 6 = 36 kg.
