Q. A container has a mixture of two liquids in the ratio 7:3. If 20 liters of the mixture is removed, what is the new ratio if the remaining mixture is 50 liters?
A.
7:3
B.
6:4
C.
5:5
D.
8:2
Solution
Initial volume = 50 + 20 = 70 liters. A = (7/10) * 70 = 49 liters, B = 21 liters. New ratio = 49:21 = 7:3.
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 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%.
Q. A mixture of two chemicals A and B is in the ratio 1:2. If 30 liters of chemical B is added, what will be the new ratio if the original mixture was 15 liters?
A.
1:3
B.
1:2
C.
1:4
D.
1:5
Solution
Original mixture = 15 liters (A = 5, B = 10). After adding 30 liters of B, new B = 40. New ratio = 5:40 = 1:8.
