A merchant has 1000 kg of sugar part of which he sells at 8 profit and the rest at 18 profit He gain...........

Explanation:

Profit of first part         Profit of second part

        8%                                 10%

                           14%        

        4%                                   6%

So, ratio of 1st and 2nd parts = 4 : 6 = 2 : 3.

Therefore, Quantity of 2nd kind = (3/5 x 1000)kg = 600 kg.

Hence, option 1 is the correct answer.
