Answer 1

➤ Given :-

Total books brought :- 5400

Total books sold :- 4050

➤ To Find :-

Percent of books did not sold............

➤ Formula required :-

$\longrightarrow \tt \large \orange {\boxed{ \tt \frac{\gray {Books \: not \: sold} }{ \gray{Total \: Books}} \gray{\times 100 }}}$

➤ Solution :-

Books not sold :-

$\tt \to5400 - 4050$

$\tt \to1350$

Now,

Percent of books not sold :-

$\tt \to \dfrac{1350}{5400} \times 100$

$\tt \to \dfrac{1350}{ \cancel{5400}} \times \cancel{100} = \dfrac{1350}{54}$

$\tt \to \cancel \dfrac{1350}{54} = 25 \bf\%$

$\Huge\therefore$25 $\bf\%$ of the books were not sold.

Answer 2

Answer:

Nikhil bought 5,400 books in a month and sold 4,050 books.

Step-by-step explanation:

He could not sell books = 5400 - 4050

= 1350

Formula required

$\frac{books \: not \: sold}{total \: no. \: of \: books} \times 100$

The per cent of books he could not sell =

$\frac{1350}{5400} \times 100$

= 25% books could not sell
