In a mixture, the ratio of juice and water is 4 : 3. By adding 6 litre water the ratio of juice and water will be 8 : 7. What is the amount of juice in the original mixture?

Correct Answer: 15.5

Explanation:

Number of liters of water in 150 liters of the mixture = 20% of 150 = 20/100 x 150 = 30 liters.
P liters of water added to the mixture to make water 25% of the new mixture.
Total amount of water becomes (30 + P) and total volume of mixture is (150 + P).
(30 + P) = 25/100 x (150 + P)
120 + 4P = 150 + P => P = 10 liters.

Correct Answer: 10 lit

Explanation:

Number of liters of water in 150 liters of the mixture = 20% of 150 = 20/100 x 150 = 30 liters.
P liters of water added to the mixture to make water 25% of the new mixture.
Total amount of water becomes (30 + P) and total volume of mixture is (150 + P).
(30 + P) = 25/100 x (150 + P)
120 + 4P = 150 + P => P = 10 liters.

Correct Answer: 5

Explanation:

Let x litre pepsi is required.

 

 

(10-9)=1           :                3=(9-6)

 

Therefore  in 1:3 one part = 5 

 

=>  x= 5 litres

Correct Answer: 320 ml

Explanation:

Here total parts of milk and water in the solution is 6+2 = 8 parts.

1part = 640/8 = 80

 

old mixture contains 6parts of milk and 2 parts of water(6:2).

 

To get new mixture containing half milk and half water, add 4parts of water to the old mixture then 6:(2+4) to make the ratio same.

i.e, 4 x 80 = 320 ml.

Correct Answer: 2:1

Correct Answer: 56

Explanation:

Let the amount of juice and water in original mixture '4x' litre and '3x' litre respectively.

According to given data,

4x/3x+6 =8/7

28x=24x+48

28x?24x=48

4x = 48

x = 12

Amount of juice = 4x = 4×12 = 48 litre.

Correct Answer: 4 : 9

Explanation:

Let the amount of juice and water in original mixture '4x' litre and '3x' litre respectively.

According to given data,

4x/3x+6 =8/7

28x=24x+48

28x?24x=48

4x = 48

x = 12

Amount of juice = 4x = 4×12 = 48 litre.

Correct Answer: 21 litres

Explanation:

Suppose the two liquids A and B are 7x litres and 5x litres respectivel Now, when 9 litres of mixture are taken out,

Now, when 9 liters of liquid B are added

 

 

Correct Answer: 20 ltr

Explanation:

Let initial quantity be Q, and final quantity be F

F = Q(1 - 8/Q) 4

=> Q = 20

Correct Answer: 10

Explanation:

Let initial quantity be Q, and final quantity be F

F = Q(1 - 8/Q) 4

=> Q = 20
