1) 1 ----- 20 kj
10 ---- x = 200 kj
Oʻzi chala parchalanishda
180 g glukozdan 200 kj energiya
ajraladi.
180 --------- 200 kj
x ----------- 200 kj
x = 180 g

2) 1 ------- 20 kj
70 ----- 1400 kj
Toʻliq parchalanishda 2800 kj
180 ------- 2800 kj
x ------- 1400 kj
x = 90 g glukoza
Jami parchalangan glukoza
180 + 90 = 270
Javob: B) 270

Yechimi
I Usul
Oqsil(x) Yog(y) va Uglevod(y)= 100%
x.
x+y = 100% x+28 = y
100-28 = 72
72/2 = 36
36(oqsil)
36+28 = 64(url,yog'
36-2 = 34(uglevod)
64-34 = 30(yog)
4280--------100
1284=x-------30
1284/38,9 = 33gr(yog')
II Usul
Oqsil(x) yog' van uglev(y)
x+y = 100
y-x = 28
x = 36
36-2 = 34(uglev)
36+34 = 70
100%-70% = 30(yog')
4280-------100%
1284=x-----30%
1284/38,9 = 33gr
