DNK da A+S+G yig'indisi T larni sonidan 3,5 barobar ko'p. Vodorod bog'lar soni esa 690 ni tashkil qilsa , S lar sonini toping.
A) 120
B) 150
C) 130
D) 140

1) T soni noma'lum bo'lgani uchun o'zimizdan 10ta deb olamiz👇
T → 10ta | A → 10ta
3,5•10=35ta➫ ( A+G+S)
35-10=25ta➫ ( G+S)
25:2=12,5ta➫ G
2) Vodorod bog'lar sonini topib olamiz↓
12,5•3=37,5ta H bog'➪︎G va S o'rtasida
10•2=20ta H bog'➪︎A va T o'rtasida
37,5+20=57,5ta➪︎ jami H bog'
3) Proporsiya tuzib olamiz ✓
57,5ta H bog' ---------- 12,5ta S
690ta H bog' -------- x=150ta S
