Question

A dishonest merchant sells his grocery using weights 15% less than the true weights and makes a profit of 20%. Find his total gain percentage.

Answer 1

Answer:

41.17%

Step-by-step explanation:

Let us consider 1 kg of grocery bag. Its actual weight is 85% of 1000 gm = 850 gm.  

Let the cost price of each gram be Re. 1. Then the CP of each bag = Rs. 850.

SP of 1 kg of bag = 120% of the true CP

Therefore, SP = 120/100 * 1000 = Rs. 1200  

Gain = 1200 – 850 = 350

Hence Gain % = 350/850 * 100 = 41.17%
