Answer 2

Answer:

The number of books of weight 2 and half kg is 4 books .

Step-by-step explanation:

Given as :

The weight of each pile of book = 600 grams

Let The number of books of weight 2 and half kg = n books

Or, The number of books of weight 2500 grams = n books

According to question

Applying unitary method

∵ The number of books having weight 600 grams = 1

So, The number of books having weight 1 gram = $\dfrac{1}{600}$

∴ The number of books having weight 2500 grams = $\dfrac{1}{600}$ × 2500

Or, n = $\dfrac{2500}{600}$

i.e n = 4.167 ≈ 4

So, The number of books of weight 2 and half kg = n = 4 books

Hence, The number of books of weight 2 and half kg is 4 books . Answer
