Question

A man sold a watch at a loss of 10 percent. If he had taken Rs.90 more, there would have been a gain of 5 percent. Find the CP of that watch. *

Answer 1

Answer:

He sold his watch at loss of 5%. If he sells his watch for Rs. 56.25 more, he would gain 10%. It means that

• 15% = Rs. 56.25.

So,

• 1% = 56.25/15.
• 100% = (56.25 *100)/15 = Rs. 375.

Therefore, the cost price of the watch is Rs. 375.
