A merchant has 1000 kg of sugar, part of which he sells at 8% and the remaining at 18% profit. He gains 14% on the whole. Find the quantity of sugar that he sold at 18% profit.
Solution
Correct Answer: Option C
মনে করি ,
18% লাভে বিক্রয়কৃত চিনির পরিমাণ x kg
8% লাভে " " " " (1000-x) "
প্রশ্নমতে ,
x×18% +(1000-x)×8% =1000×14%
বা,(x×18)/100 + (100-x)×8/100 =(1000×14)/100
বা,18x+8000-8x=14000
বা, 18x-8x=14000-8000
বা,10x=6000
x=600 kg
