Q. A solution is made by mixing 60 liters of a 20% salt solution with 40 liters of a 30% salt solution. What is the percentage of salt in the new mixture?
A.
24%
B.
26%
C.
28%
D.
30%
Solution
Salt in 60 liters of 20% solution = 0.2 * 60 = 12 liters. Salt in 40 liters of 30% solution = 0.3 * 40 = 12 liters. Total salt = 12 + 12 = 24 liters. Total mixture = 60 + 40 = 100 liters. Percentage of salt = (24/100) * 100 = 24%.
Q. A store increases the price of a product by 12% and then offers a discount of 12% on the new price. What is the net effect on the price?
A.
0%
B.
1.44% increase
C.
1.44% decrease
D.
2.4% increase
Solution
Let the original price be 100. New price after increase = 100 + 12 = 112. Discount = 12% of 112 = 13.44. Final price = 112 - 13.44 = 98.56. Net effect = (98.56 - 100) / 100 * 100 = -1.44%.
Q. A store increases the price of a product by 20% and then offers a 10% discount on the new price. If the original price is $50, what is the final price after the discount?
A.
$54
B.
$55
C.
$56
D.
$57
Solution
New price after 20% increase = 50 + 10 = 60. Discount = 10% of 60 = 6. Final price = 60 - 6 = $54.
