Question

There are 8 textbooks and 20 notebooks scattered on your study table. you have to arrange these such way that they occupy minimum space on the table and each bunch has equal no of books. find the number of bunch and also find the number of books.

Answer 1

Answer:

We will have 7 bunches, each containing four books.

Step-by-step explanation:

In this question, we need to find the GCD of 8 and 20 for us to get the number of books in each bunch and the number bunches.

To get the GCD, we need to list down the prime factors of the two numbers.

We do this below:

8 = 2 × 2 × 2

20 = 2 × 2 × 5

Here,the GCD is given by: 2 × 2 = 4

Therefore, each bunch will have a total of four books.

For the 8 text books we will have: 8/4 = 2 bunches

For the 20 notebooks we will have: 20/4 = 5 bunches

So we have a total of: 5 + 2 = 7 bunches
