Javob va yechimni ko‘rish
Javob: 300
Berilgan sonlarni juft‑juft yig‘indiga ajrating: $12+24+36$ va $64+76+88$.
Birinchi uchta son $12,24,36$ hammasi $12$ ga bo‘linadi, shuning uchun $12(1+2+3)=12\cdot6=72$.
Ikkinchi uchta son $64,76,88$ ham $4$ ga bo‘linadi, $4(16+19+22)=4\cdot57=228$.
Endi ikki qismni qo‘shamiz: $72+228=300$.
Demak, to‘g‘ri javob **C) 300**.
