- Let the capacity of glass is 15 unit.
Milk in first glass = (1/3)*15 = 5 units
Water in first glass = 15 - 5 = 10 units
Milk in first glass = (2/5)*15 = 6 units
Water in first glass = 15 - 6 = 9 units
total milk = 5+6 = 11 units
total water = 10 + 9 = 19 units
Milk : Water = 11:19 - 6 years agoHelpfull: Yes(9) No(0)
- let us assume capacity of glass as x
so, milk in the glass is x/3 and 2x/5
therefore filled with water
quantity of water in glass is x-x/3=2x/3 and x-2x/5=3x/5
now both glasses are mixed in a tumbler
So total quantity of milk there is x/3 + 2x/5 = 11x/15
Total quantity of water is 2x/3 + 3x/5= 19x/15.
So the ratio of milk to water is (11x/15) / 19x/15=11/19 (this is the ratio) - 6 years agoHelpfull: Yes(3) No(1)
- the water in first glass which 1/3 part full by milk = 1-1/3=2/3 part.
the water in the second glass which 1/4 part full by the milk=1-1/4=3/4.
Total water in the pot=2/3+3/4=17/12.
total milk in pot=1/3+1/4=7/12.
ratio=7/12รท17/12 = 7:17 ans. - 5 years agoHelpfull: Yes(0) No(1)
