Correct answer: A. 40% loss40% हानि

Explanation

Let CP of one article be Re 1. SP of 10 articles = CP of 6 = Rs 6, so SP of one = 0.6. Loss = 1 − 0.6 = 0.4, so loss % = 40%.माना एक वस्तु का क्रय मूल्य 1 रुपया है। 10 वस्तुओं का विक्रय मूल्य = 6 वस्तुओं का क्रय मूल्य = 6 रुपये, अतः एक का विक्रय मूल्य = 0.6। हानि = 1 − 0.6 = 0.4, अतः हानि % = 40%।
