A bottle is sold at a loss of 9%. Had it sold for Rs. 15 more, a profit of 25/2% would have gained. What is the cost price of the bottle (approx)?

A) Rs. 32 B) Rs. 35

Selling price of the bottle = Rs. 100 - Rs. 9 = Rs. 91

Then, from the given data,

=> 112 (1/2) - 91 = 15

=> 21 (1/2) = 15

=> 43 = 15

Then 100 = ?

1500/43 = 34.885 =~ 35

Hence, the cost price of the bottle = Rs. 35
