Question

Vaaaa roggggggg!!!!!

Answer 1

a) n+n+1+n+2=450,3n=450-3=447, n=447/3=149 tr rosii, 149+1=150 a, 150+1=151 g

b) n+n+2+n+4=450, 3n=450-6=444, n=148r, 150a, 152g

c) r=(a+g)/2, a=20+g, r+a+g=450, inlocuim r si a, (g+20+g)/2+g+20+g=450,

g+10+g+20+g=450, 3g=450-30=420, g=420/3=140 galbeni, 140+20=160 albi

r=(140+160)/2=300/2=150 rosii

d) a=rx40/100=0,4r, g=rx10/100=0,1r deci r+0,4r+0,1r=450, 1,5r=450, r=450/1,5=300 rosii, 0,4x300=120 albi, 0,1x300=30 galbeni
