Gopal bought 51 books at ₹1,120 per book from one shop and 45 books at ₹920 per book from another. What is the average price (in ₹) he paid per book?​

Correct option is A

Given:

Gopal bought 51 books at ₹1120 each and 45 books at ₹920 each

Formula Used:

Average Price = $$\frac{(n_1 \times p_1) + (n_2 \times p_2)}{n_1 + n_2}$$​​

Solution:

​$$n_1 = 51, \quad p_1 = 1120, \quad n_2 = 45, \quad p_2 = 920$$​​

Total Cost = $$(51 \times 1120) + (45 \times 920)$$​​

= 57120 + 41400 = 98520

Total Books = 51 + 45 = 96

Average Price = $$\frac{98520}{96}$$​ = ₹1026.25
