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.
- A. 400kg
- B. 400kg
- C. 400kg
- D. 400kg
Answer: Option C
Explanation:
ধরি, 18% profit - এ বিক্রি করে x Kg
8% profit এ বিক্রি করে ( 1000 - x) Kg
(1000 - x) × 8/100 + x × 18/100 = 1000 এর 14/100
8000 - 8x + 18x = 14000
10x = 14000 - 8000
x = 6000/10
x = 600
