A man bought 15 articles at ₹70 each, 13 at ₹60 each and 12 at ₹65 each. The average price per article (in ₹) is:
Answer & explanation
Correct answer: option 1
Cost of 15 articles
15 × 70 = Rs.1050
Cost of 13 articles
13 × 60 = Rs.780
Cost of 12 articles
12 × 65 = 780
The average price of the article = \(\frac{1050 + 780 +780}{15 + 13 + 12}\) = \(\frac{d}{d}\) = 65.25
