ok KO of mass 550 gram has three ingredients flour sugar and raisins there is twice as much as flour sugar and one and a half times as much as sugar is racing how much flour is there

2S = F

1.5R = S or R = S/1.5

So flour F and sugar S and raisins R

F + S + R = 550

2S + S + S/1.5. = 550

3S + 1.5S + S = 550*1.5

5.5 S = 550*1.5

S = 100*1.5

S = 150

R= 100

And so flour ie, F = 300
