Let x kg dry grapes be obtained. Then, solid part in fresh grapes = solid part in dry grapes
0.2*3.4=0.85 * X
x=0.8

1kg fresh grapes=800gm water
1kg dried grapes=150gm water
800gm fresh grape=150gm dried grape
0.8kg fresh grape=.15kg dried grape
Now
1kg fresh grape=0.15/0.8 kg dried grapes
So
3.4 kg fresh grape=3.4*(0.15/0.8)
=51/80
=0.6375 or 0.6

ans--(c)

1 kg of fresh grapes=200gm of pure grape

200gm of pure grape=0.85*x (x=total weight of dried grape)

x=200/0.85=

Hence,

1kg of fresh grapes produces---->200/0.85 kg of dried grapes

so 3.4 kg of fresh grapes produces------>200/0.85 * 3.4kg of dried grapes=800gm=0.8kg
