in what ratio must water be mixed with milk to gain 20% by selling the mixture at cost price
Read Solution (Total 4)
-
- 100 liter milk sale has for 120 liter to make 20% profit
100milk + 20 water=120 liter
so water:milk =====1:5 - 12 years agoHelpfull: Yes(31) No(1)
- let the cost price be x
To get the profit of 20%, the x need to be 1.2 times the new price
So the actual quantity of milk to be sell=(x*100)/120=5x/6
Now to make the quantity equal to x, water required=1-(5x/6)=x/6
Therefore the ratio of water to milk =x/6:5x/6=1:5 - 12 years agoHelpfull: Yes(11) No(6)
- in 1:5 ratio must water be mixed with milk to gain 20% by selling the mixture at cost price.
To gain 20% milk should be sold at 20% more value than cost price. But as the milk is sold at cost price, so to make gain of 20% one must add 20% water with the milk. - 12 years agoHelpfull: Yes(5) No(6)
- 1:5
cp=sp
let sp=1
cp=100/120 *1
5/6
by mixture and alligation cp of water =0
cp of milk=1
0 1
5/6
1/6 5/6
ratio would be (1/6)/(5/6)=1:5 - 10 years agoHelpfull: Yes(3) No(0)
