Answer 2

Required Answer

Given

• Cost of 12 books is Rs.960.

To Find

• Cost of 44 books.

Concept

Here, we have the value of 12 books. We have to find the value of 45 books. So first, we will find the value of 1 book. And then we will multiply and find the answer for cost of 45 books.

Solution

⇨ Cost of 12 books = Rs.960

⇨ Cost of 1 book = 960/12

⇨ Cost of 1 book = Rs.80

So, we got the cost of 1 book. Now we will multiply the sum and find the cost of 45 books.

⇨ Cost of 45 books = 80 × 45

⇨ Cost of 45 books = Rs.3600

So, the cost of 45 books is Rs.3600.

Hence, Option (3) is the Answer
