Q. A mixture contains 20% sugar. If 5 kg of sugar is added to the mixture, what will be the new percentage of sugar if the total weight of the mixture becomes 30 kg?
A.
25%
B.
20%
C.
30%
D.
15%
Solution
Initially, the mixture has 20% sugar. After adding 5 kg, the new sugar content is (0.2 * 25) + 5 = 10 kg. The new percentage is (10/30) * 100 = 33.33%, which rounds to 25%.
Q. A mixture contains 30% orange juice and 70% water. If 5 liters of the mixture is taken out and replaced with 5 liters of pure orange juice, what will be the new percentage of orange juice in the mixture?
A.
40%
B.
50%
C.
30%
D.
60%
Solution
Removing 5 liters removes 1.5 liters of orange juice. New orange juice = 5 + (30% of 5) = 5 + 1.5 = 6.5 liters in 10 liters = 65%.
Q. A mixture contains 40% alcohol and 60% water. If 5 liters of the mixture is taken out and replaced with 5 liters of pure alcohol, what will be the new percentage of alcohol in the mixture?
A.
50%
B.
55%
C.
60%
D.
65%
Solution
After removing 5 liters of the mixture, the remaining alcohol is 0.4 * (total volume - 5) + 5 liters of pure alcohol.
Q. A mixture contains 60% fruit juice and 40% water. If 5 liters of water is added, what will be the new percentage of fruit juice in the mixture if the total volume becomes 25 liters?
A.
50%
B.
60%
C.
40%
D.
70%
Solution
Initial fruit juice = 0.6 * 20 = 12 liters. New total = 25 liters. New percentage = (12/25) * 100 = 48%.
Q. A mixture contains 60% of liquid X and 40% of liquid Y. If 10 liters of liquid Y is added, what will be the new percentage of liquid X in the mixture if the total volume becomes 30 liters?
A.
50%
B.
40%
C.
60%
D.
70%
Solution
Initial volume of Y = 40% of 20 liters = 8 liters. New volume of Y = 8 + 10 = 18 liters. Volume of X = 30 - 18 = 12 liters. Percentage of X = (12/30) * 100 = 40%.
Q. A mixture contains 60% of liquid X and 40% of liquid Y. If 5 liters of liquid Y is added, what will be the new percentage of liquid X in the mixture if the total volume becomes 25 liters?
A.
60%
B.
50%
C.
40%
D.
70%
Solution
Initial volume of X = 60% of 20 liters = 12 liters. New total = 25 liters. New percentage of X = (12/25) * 100 = 48%.
Q. A mixture contains two types of fruit juice in the ratio 3:5. If the total volume of the mixture is 40 liters, how much of the first juice is there?
A.
15 liters
B.
20 liters
C.
25 liters
D.
30 liters
Solution
In a 3:5 ratio, the total parts = 3 + 5 = 8. First juice = (3/8) * 40 = 15 liters.
Q. A mixture is made by combining 3 parts of liquid A and 5 parts of liquid B. If the total volume of the mixture is 80 liters, how much of liquid A is there?
A.
30 liters
B.
40 liters
C.
50 liters
D.
20 liters
Solution
Total parts = 3 + 5 = 8. Volume of A = (3/8) * 80 = 30 liters.
Q. A mixture of 40 liters contains 10% salt. If 5 liters of the mixture is removed and replaced with water, what is the new percentage of salt?
A.
8%
B.
9%
C.
10%
D.
11%
Solution
Initial salt = 10% of 40L = 4L. After removing 5L, salt left = 4L - (10% of 5L) = 4L - 0.5L = 3.5L. New volume = 40L. New percentage = (3.5/40) * 100 = 8%.
