Read Solution (Total 6)
-
- 3/2 lit costs Rs 20. so 60 lit will cost Rs800.
now , let say x lit of water will be added.....
as the mix. worth Rs32/3 per lit.
(60+x)32/3=800
(60+x)32=2400
60+x=75
x=15
so 15 lit water will be added.

- 1/4 liter costs 10 rs
3/4 water costs 0 rs
----------------------
1 lt mix cost 10 rs
so 3/4 of 60 lit is 45 liters of water must be added - 12 years agoHelpfull: Yes(1) No(4)
- 1 1/2 => 3/2
3/2litres=Rs.20
1litre=Rs.40/3
10 2/3=> 32/3
40/3 - 32/3 = 8/3
40/3 per litre => Rs.1 per 3/40litre
For Rs.8/3 = 8/3 X 3/40 = 0.2litres
for 60litres 60X0.2=12litres of water should be added. - 10 years agoHelpfull: Yes(1) No(1)
- cost of 3/2 litter is=20rs
cost of 1 litter is 40/3
we have to make cost 32/3
my the formula of mixture and alligation the ratio of milk and water should 4:1
so 60/4=15 - 8 years agoHelpfull: Yes(0) No(0)
- CP of 1.5 L of milk= Rs 20
CP of 60 L =800
CP of water=0
32/3=800+0/60+x where x is the liter of water added
(60+x) * 32 = 3 * 800
1920 + 32x =2400
32x=480
x=15 L - 3 years agoHelpfull: Yes(0) No(0)
