employees, into the other's factory. Because of this, both companies
became highly protective of their chocolate-making processes. It was a
combination of this secrecy and the elaborate, often gigantic, machines
in the factory that inspired Dahl to write the story. But here we will read

‘CHARLIE AND THE CHOCOLATE FACTORY’

INTRODUCTION

The story was originally inspired by Roald Dahl's experience of chocolate

companies during his school days. Cadbury would often send test

packages to the schoolchildren in exchange for their opinions on the new

products. At that time (around the 1920s), Cadbury

and Rowntree's were England's two largest chocolate makers and they

each often tried to steal trade secrets by sending spies, posing as

employees, into the other's factory. Because of this, both companies

became highly protective of their chocolate-making processes. It was a combination of this secrecy and the elaborate, often gigantic, machines

in the factory that inspired Dahl to write the story. But here we will read

only an extract from “Charlie and the Chocolate factory.”

WRITER

Charlie and the Chocolate Factory is a 1964 children's novel by British

author Roald Dahl. The story features the adventures of young Charlie

Bucket inside the chocolate factory of eccentric chocolatier Willy Wonka.

SUMMARY

The Bucket family—the hero of the story, Charlie Bucket; his parents, Mr.

and Mrs. Bucket; and his four grandparents, Grandpa Joe, Grandma

Josephine, Grandpa George, and Grandma Georgina—is a loving but

poor family. They live in a small house with only one bed, which the four

grandparents share. Charlie and his parents sleep on mattresses on the floor. Mr. Bucket works in a toothpaste factory and barely earns enough

money to feed his family. They are forced to subsist on bread and

margarine for breakfast, boiled potatoes and cabbage for lunch, and

cabbage soup for supper. Charlie longs for more filling foods, especially

chocolate, which he receives only once a year on his birthday. On that

day he gets one bar of Wonka chocolate, which he saves for months and months. Charlie’s house sits on the outskirts of a large town that is

famous for the Wonka chocolate factory. Charlie must pass by the

Wonka chocolate factory every day on his way to and from school. Each

day as he walks by the factory’s colossal iron gates, Charlie inhales deeply

and prays that someday he will get to venture inside the factory.

THINGS TO LEARN

The opening chapter of the story creates a stark dichotomy between what Charlie has and what he does not have, which demonstrates

Charlie’s infinitely patient and humble character. Charlie’s four

grandparents—all of whom are over ninety—require constant care

from his mother, and his father’s meagre wages barely buy enough

food for their family.

SUBTRACTION OF FRACTIONS

To subtract like fractions:

Q1. Subtract 52 − 51

Step 1: The denominators are same as they are like fractions. So we just have to subtract the numerators.

So, 52 − 51 = 51

To subtract unlike fractions:

Q2. Subtract 32 − 51

Step 1: The denominators are different as these are unlike fractions. So, we need to find the lowest common multiple (LCM) of 3 and 5.

The LCM of 3 and 5= 15

Step 2: Convert 32 and 51 into like fractions with denominator 15.
