SSC GD 2024 PYQ — Question 56

The correct answer is option 3 i.e. 35 %.

Marked price of laptop = 80% above the cost price

Discount = 25%

SP = MP $\times{ {100 -D}\over 100}$

Profit = SP - CP

Profit percentage = ${P \over CP} \times 100$

Let the cost price of the laptop be 100x.

According to the given question,

MP = 180% of 100x

⇒ MP = 180x

SP = 180x $\times{ {100 - 25}\over 100}$

⇒ SP =  180x $\times{75\over 100}$ 

⇒ SP = 135x

Now, profit = 135x - 100x = 35x

Profit percentage = ${35x \over 100x} \times 100$ = 35%

Hence the profit percentage is 35%.
