Q. A solution contains 40% sugar. If 10 liters of this solution is mixed with 5 liters of pure sugar, what is the percentage of sugar in the new solution?
A.
50%
B.
60%
C.
70%
D.
80%
Solution
Sugar in 10L = 40% of 10L = 4L. Total sugar = 4L + 5L = 9L. Total volume = 10L + 5L = 15L. Percentage = (9/15) * 100 = 60%.
Q. A solution is made by mixing 15 liters of a 30% acid solution with 5 liters of a 50% acid solution. What is the percentage of acid in the new solution?
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?
A.
20 kg
B.
30 kg
C.
25 kg
D.
15 kg
Solution
In a 2:3 ratio, total parts = 2 + 3 = 5. First type = (2/5) * 50 = 20 kg.
Q. A store increases the price of a product by 25% and then offers a 20% discount. If the original price was $80, what is the final price after the discount?
A.
$80
B.
$85
C.
$90
D.
$95
Solution
New price after increase = 80 + (25% of 80) = 80 + 20 = $100. Discount = 20% of 100 = 20. Final price = 100 - 20 = $80.
Q. A store increases the price of a product by 25% and then offers a discount of 20%. If the original price was $80, what is the final price after the discount?
A.
$72
B.
$76
C.
$80
D.
$64
Solution
New price after increase = 80 + 0.25 * 80 = 100. Discount = 20% of 100 = 20. Final price = 100 - 20 = $80.
