Amit bought 51 books at ₹1,120 per book from one shop and 49 books at ₹900 per book from another. What is the average price (in ₹) he paid per book?​

Correct option is C

Given:

Books from first shop = 51 at ₹1120 each

Books from second shop = 49 at ₹900 each

Formula Used:

Average price = Total cost ÷ Total number of books

Solution:

Average price = $$\frac{(51 \times 1120 + 49 \times 900)}{51 + 49}$$​​

​$$= \frac{57120 + 44100}{100}$$​​

$$= \frac{101220}{100}$$​ = ₹1012.20
