word Problem 10 (Profit for new price and cost price)
Problem 10: A man sold his watch at loss of 5%. He had sold it for Rs 56.25 more he would have gained 10%. Find the cost price of the watch.
a. Rs 300 b. Rs 375 c.Rs 400 d. Rs 200

Loss was 5% of CP
But fromula for loss is
So his sale price was 19y/20
Now come to the situation as wished in the question
If had he sold it with more 56.25 Rs then sale price would have been 19y/20+56.25 Rs
i-e
Wished sale price;
and in this case he would have earned profit of 10% of his CP
Wished profit;
But formula for profit is
So, the cost price for the watch is Rs 375
