Question

Anya sold two coolers for Rs. 3990 each. On selling one cooler, she gained 5% and on selling

other she suffered a loss of 5%. Find her overall gain or loss in rupees​

Answer 1

Answer:

₹20 loss

Step-by-step explanation:

Selling Price of first cooler = ₹3990

Gain = 5%

=> (100+5)% of CP = SP

=> 105% of CP = ₹3990

=> 105/100 × CP = ₹3990

=> CP = ₹3990 × 20/21

=> CP = ₹3800

Selling Price of second cooler = ₹3990

Loss = 5%

=> (100-5)% of CP = SP

=> 95% of CP = ₹3990

=> 95/100 × CP = ₹3990

=> CP = 3990 × 20/19

=> CP = ₹4200

Total CP = ₹3800 + ₹4200 = ₹8000

Total SP = ₹3990 + ₹3990 = ₹7980

CP > SP,

Loss = CP - SP = ₹8000 - ₹7980 = ₹20
