Answer:
My Dear Friend My Answer Is Correct
Step-by-step explanation:
Let x be the cost price.
Then, marked price = x * 120/100 = 1.2 x
Sale price after discount = 1.2 x * 82/100 = 0.984 x
Now , loss = Rs.20 = x — 0.984 x = 0.016 x
Hence, x = 20/0.016 = Rs. 1250
Marked price = 1.2 * 1250 = Rs. 1500
Sale price = 0.82 * 1500 = Rs. 1230
