Q. A store offers a 25% discount on a jacket that is originally priced at $80. If the store then increases the price by 10% after the discount, what is the final price of the jacket?
A.
$70
B.
$75
C.
$78

Solution
Discounted price = $80 - (25% of $80) = $80 - $20 = $60. After a 10% increase, final price = $60 + (10% of $60) = $60 + $6 = $66.

Solution
First discount: $200 - (30% of $200) = $200 - $60 = $140. Second discount: $140 - (10% of $140) = $140 - $14 = $126.
Q. A student scored 75% in Mathematics and 85% in Science. If the total marks for each subject are 200, what is the student's overall percentage? (2023)
A.
80%
B.
82.5%
C.
78%
D.
76%
Solution
Total marks obtained = 75% of 200 + 85% of 200 = 150 + 170 = 320. Total marks = 200 + 200 = 400. Overall percentage = (320/400) * 100 = 80%.
