Answer 1

Answer:

Step-by-step explanation:

Amount of sugar bought at 13.50 per kg =80 kg

Cost price of this set of sugar =80×13.5= Rs. 1080

Amount of sugar bought at 16 per kg =120 kg

Cost price of this set of sugar =120×16= Rs. 1920

Total cost price =1920+1080= Rs. 3000

Total weight of sugar =80+120=200 kg

∴ To gain 16% profit, Selling Price =  

100

116

​

×3000=3480

Selling price per kg =  

200

3480

​

=  rs . 17.40
