Answer:
Therefore total number of books = 250 Books
Step-by-step explanation:
Average cost of the Book = Rs 380.00
No of Books Purchased at Rs 350 = 100 Books
Total cost of 100 Books = 350 x 100 = Rs 35,000.00
Cost of remaining books = RS 400
Let the remaining books be X
Total cost for X books = Rs 400X
Total number of books = X + 100
Its given that
(35,000 + 400X)/(X + 100) = 380
35,000 + 400X = 380(X + 100)
is 35,000 + 400X = 380X + 38000
400X - 380X = 38,000 - 35,000
20X = 3,000
Therefore X = 3,000/20 = 150 Books
Therefore total number of books = 100 + 150 = 250 Books
