What will b wt of dried grapes when we begin with 20 kg fresh grapes?
Read Solution (Total 5)

- 2.5 will be answer
in 20 kg there was 18 kg water amd the rest 2 kg was pure grapes which will never reduce.
So when the grapes get dried and there is only 20% water then rest 80 kg will be pure grapes which is 2 kg.
let x be total quantity then -----x*80/100=2
on solving x=2.5 - 9 years agoHelpfull: Yes(20) No(0)
- 2.5kg is answer
puregrape=10% of 20=2kg
puregrape=80% of drygrape
2 = 80% * drygrape
drygrape= 2*100/80 =5/2=2.5kg - 9 years agoHelpfull: Yes(9) No(0)
- ans 25
fresh graps water=90%
flush=10%
weight of fresh grapes in flush=20 .so (10/100)*x=20
weight=20
even when the fruit was dried it does not change the weight of flush so
after dried water = 20% and flush= 80%
(80/100)*x=20
so weight of dried fruit is 25 - 9 years agoHelpfull: Yes(4) No(16)
- (10%*20)=(80%*x)
0.1*20=0.8*x
X=2.5kg - 8 years agoHelpfull: Yes(3) No(0)
- (80*x)/100=(10*20)/100 :(-> equating the core part in both)
- 9 years agoHelpfull: Yes(0) No(0)
