Q. A mixture of two liquids A and B is in the ratio 4:1. If 10 liters of liquid A is added to the mixture, what will be the new ratio if the total volume becomes 50 liters?
A.
5:1
B.
4:1
C.
8:1
D.
3:1
Solution
Initial volume = 50 - 10 = 40 liters. A = (4/5) * 40 = 32 liters, B = 8 liters. New ratio = 32:8 = 4:1.
Q. A mixture of two liquids A and B is in the ratio 4:1. If 25 liters of liquid A is added to the mixture, what will be the new ratio if the original mixture was 20 liters?
A.
5:1
B.
4:1
C.
3:1
D.
2:1
Solution
Original mixture = 20 liters (A = 16, B = 4). After adding 25 liters of A, new A = 41, B = 4. New ratio = 41:4 = 5:1.
Q. A mixture of two liquids X and Y is in the ratio 1:4. If 10 liters of liquid Y is added, what will be the new ratio if the original mixture was 20 liters?
A.
1:5
B.
1:4
C.
1:3
D.
1:2
Solution
Original mixture = 20 liters (X = 4, Y = 16). After adding 10 liters of Y, new Y = 26. New ratio = 4:26 = 1:5.
Q. A mixture of two types of fruit juice is in the ratio 1:2. If the total volume of the mixture is 90 liters, how much of the first type of juice is there?
A.
30 liters
B.
45 liters
C.
60 liters
D.
15 liters
Solution
Total parts = 1 + 2 = 3. First type of juice = (1/3) * 90 = 30 liters.
Q. A mixture of two types of fruit juice is in the ratio 2:3. If 10 liters of juice B is added, what will be the new ratio if the total volume becomes 50 liters?
A.
2:3
B.
3:2
C.
1:4
D.
4:1
Solution
Initial volume = 50 - 10 = 40 liters. A = (2/5) * 40 = 16 liters, B = 24 liters. New ratio = 16:24 = 2:3.
Q. A mixture of two types of fruit juice is in the ratio 5:3. If the total volume of the mixture is 64 liters, how much of the first type of juice is there?
A.
40 liters
B.
32 liters
C.
24 liters
D.
16 liters
Solution
Total parts = 5 + 3 = 8. First type = (5/8) * 64 = 40 liters.
Q. A mixture of two types of fruit juice is made in the ratio 5:3. If the total volume of the mixture is 64 liters, how much of the first type of juice is used?
A.
40 liters
B.
32 liters
C.
25 liters
D.
20 liters
Solution
In a 5:3 ratio, the total parts = 5 + 3 = 8. First type of juice = (5/8) * 64 = 40 liters.
Q. A solution is made by mixing two liquids in the ratio 3:4. If the total volume of the solution is 70 liters, how much of the second liquid is there?
A.
30 liters
B.
40 liters
C.
35 liters
D.
20 liters
Solution
In a 3:4 ratio, the total parts = 3 + 4 = 7. Second liquid = (4/7) * 70 = 40 liters.
Q. A solution is made by mixing two types of tea in the ratio 2:3. If the total weight of the mixture is 50 kg, how much of the first type of tea is there?
