SSC CHSL 2024 PYQ — Question 74

The correct answer is option 4 i.e. 40.

Given that, SP of each fan = ₹480

Profit on one fan = 20%

Loss on second fan = 20%

SP = CP × ${100 + P }\over 100$

Also,  SP = CP × ${100 - L }\over 100$

Loss = CP - SP

According to the given question,

CP of fan sold at profit = SP × $100\over{100 + P }$

⇒ 480 × $100\over 120$ = 400

CP of fan sold at loss =  SP × $100\over {100 - L }$

⇒ 480 × $100\over 80$ = 600

Total CP = 400 + 600 

⇒ 1000

Total SP = 480 + 480 

⇒ 960

Loss = 1000 - 960

⇒ 40
