A) Rs. 1190 B) Rs. 1288
C) Rs. 1365 D) Rs. 1452
 
Answer & Explanation Answer: A) Rs. 1190

Explanation:

Let the profit be Rs. p

Then Cost price of the bag = 340p/100 = 3.4p

According to question,

3.4p + p = 1540

4.4p = 1540

p = 1540/4.4

p = 350

The profit p = Rs, 350

 

Hence, The cost price of the bag = 3.4p = 3.4 x 350 = Rs. 1190.
