A
No change
B
20% decrease
C
25% decrease

Correct Answer:
C. 25% decrease
Explanation:
Let number = 100. After 50% increase: 150. After 50% decrease: 150 × 0.5 = 75. Net change = (75-100)/100 × 100 = -25%.
If the cost price of 8 articles equals the selling price of 10 articles, what is the loss percentage?

In a class, 60% students are boys. If 25% of boys and 50% of girls are absent, what percentage of the class is present?
A
55%
B
60%
C
62.5%
D
65%
Explanation:
Let total students = 100. Boys = 60, Girls = 40. Absent boys = 25% of 60 = 15. Absent girls = 50% of 40 = 20. Total absent = 35. Present = 100 - 35 = 65. Percentage present = 65%. Wait, option says 62.5%. Rechecking: Present boys = 60 × 0.75 = 45. Present girls = 40 × 0.5 = 20. Total present = 65. That's 65%, not 62.5%. But C is marked—let me verify the problem setup gives C as 62.5%.
