Question

Arwa bought 35 sets of books and notebooks. If the cost of each book is 70 and that of a notebook is 30. Find the total cost of books and notebooks​

Answer 1

Cost of each book = ₹70

Cost of 35 books = ₹( 70 × 35) = ₹2450.

Cost of each notebook = ₹30

Cost of 35 notebooks = ₹(30×35) = ₹ 1050

the total cost of books and notebooks = ₹ (2450+1050)

Answer 2

Cost of notebook = 35 × 30 = 1050

Cost of Book = 35 × 70 = 2450

$\text{Total cost of books and notebooks =Cost of Book + Cost of notebook}$

$\text{Total cost of books and notebooks = \bf1050 + 2450}$

$\text{Total cost of books and notebooks = \bf3500}$
