In a mixture 60 litres, the ratio of milk and water 2 : 1. If this ratio is to be 1 : 2, then the quantity of water to be further added is:

Answer: Option

Explanation:

Quantity of milk = | 60 x | 2 | litres = 40 litres. | |

3 |

Quantity of water in it = (60- 40) litres = 20 litres.

New ratio = 1 : 2

Let quantity of water to be added further be *x* litres.

Then, milk : water = | 40 | . | ||

20 + x |

Now, | 40 | = | 1 | ||

20 + x |
2 |

20 + *x* = 80

*x* = 60.

Quantity of water to be added = 60 litres.

The ratio of milk to water is given as: 2:1.

Let us assume a quantity of milk is 2x ans water is x.

Therefore ,

2x + x = 60 liters (Total mixture).

3x = 60

x = 20 --------(1)

Now milk is 2x therefore 2*20 = 40 liters is milk.

Now new water is added therefore x becomes (20 + x),

now new ration is given 40 /(20+x) = 1/2,

80 = 20 + x.

x = 60 Liters.

60 lit, 2:1.

2x +1x = 60 lit,

3x = 60,

x = 60/3,

x = 20 lit.

2x +1x = 60 lit,

3x = 60,

x = 60/3,

x = 20 lit.

The ratio of milk and water in 60L is;

m=2.

w=1 (2+1)=3,

milk = 2/3, water=1/3.

milk in 60L = 2/3 * 60= 40L.

water in 60L = 1/3 * 60= 20L,

40:(20+60)=4:8= 1:2.

m=2.

w=1 (2+1)=3,

milk = 2/3, water=1/3.

milk in 60L = 2/3 * 60= 40L.

water in 60L = 1/3 * 60= 20L,

40:(20+60)=4:8= 1:2.

@All.

Simply the solution is;

Mixture = 60 litre.

The ratio is 2: 1 , so milk:water=40:20.

New ratio= 1: 2 , means milk : water should be 40:80.

Water in the new mixture should be 80.

Less water already in the mix 20.

Water to be added now is 60.

m:w=2:1

m+w=60

2x+x-=60

x=20.

m=40 w=20.

Added water be y.

40:(20+y) = 1:2.

On cross multiplication

y=60.

m+w=60

2x+x-=60

x=20.

m=40 w=20.

Added water be y.

40:(20+y) = 1:2.

On cross multiplication

y=60.

The initial quantity of milk=(2/3)*90 = 60,

Initial quantity of water=(1/3)*90 = 30,

If the ratio is to be 2:3 the water to be added;

(60Ã·(30+x)) = 2/3,

X = 60.

Initial quantity of water=(1/3)*90 = 30,

If the ratio is to be 2:3 the water to be added;

(60Ã·(30+x)) = 2/3,

X = 60.

40/20+x = 1/2.

Cross multiple;

80 = 20 + x.

x = 60.

Cross multiple;

80 = 20 + x.

x = 60.

Total = 60.

Milk: water 2:1 means 40:20.

60*40/20 = 120.

1:2 new ratio, then water added

120 = 40:80.

Then,

120*40/80 = 60.

Thank you.

40/20+x=1/2 anyone can solve it?

Initially we have 60lt in the ratio 2:1.

i.e: 40lt milk & 20lt water.

Think logically,

Our condition is to make the ratio as 1:2.

i.e: 40lt milk & 80lt water.

Then 40 : 80 it will become 1:2.

So, the required amount of water will be 80 - 20 (i.e: final quantity - initial quantity -> then we can get req amount of water to make the ratio as 1:2).

i.e: 40lt milk & 20lt water.
