Correct option (c) Gain 1%
Explanation:
Let cost price for Gopal = Rs. 100
He sold it to Ram at 10% profit. So, his selling price = 100 + 10% of 100 = 100 + 10 = Rs. 110
Now, if Ram resales it to Gopal at 10% loss, his selling price = 110 – 10% of 110 = 110 – 11 = Rs. 99 As far as Gopal is concerned, in this second transaction, by buying a Rs. 100 pen at Rs 99, he registers a gain of 1%.
