Question

There are 192 books in the library each weighing 6 kg. The books need to be discarded and, therefore, are kept equally in 8 cartoons.

What is the weight of each carton?

• A. 152 kg
• B. 144 kg
• C. 161 kg
• D. 137 kg

Answer 1

The correct option is B 144 kg

Number of books in the library = 192
Weight of each book = 6 kg

∴ Weight of all the books altogether
= (192 $\times$ 6) kg

Calculating 192 $\times$ 6 by standard method, we get:


So, weight of all the books = 1152 kg

Now these books have to be kept in 8 carton equally.

∴ Weight of each carton = 1152 $÷$ 8

Dividing 1152 $÷$ 8 by standard algorithm, we get:


The quotient is 144.

Hence, each carton weighs 144 kg.
