15%Explanation
25 % লাভে A এর বিক্রয়মূল্য ( 120 + 120 × 25/100) টাকা = 150 টাকা। B এর ক্রয়মূল্য = 150 টাকা। 10% লাভে, C এর বিক্রয়মূল্য 110 টাকা হলে ক্রয়মূল্য 100 টাকা C এর বিক্রয়মূল্য 198 টাকা হলে ক্রয়মূল্য ( 100 × 198 /110) = 180 টাকা। সুতরাং B এর বিক্রয়মূল্য 180 টাকা। B এর লাভের হার = ( 180 - 150) / (150 × 100) % = 30/(150 × 100) % = 20%Related questions
