Question

A man purchased 400 pens to sell . he found that 15 percent of them were broken. how many pens were found broken?​

Answer 1

Answer:

Total number of pens = 400

% of pens broken = 15%

Therefore, number of pens broken

=15/100×400

15×4

60 pens

Answer 2

60 pens were found broken.

Solution :

It is given that,

The total number of pens that the man purchased = 400

Percentage of the broken pens = 15%

To find : The number of pens that were found broken.

Now to find the number of broken pens, we have to multiply 400 with 15%

We have to write 15% in the fractional form. 15% can be written as :

$\frac{15}{100}$

Now,

$15\% \times 400$

$\frac{15}{100} \times 400$

$15 \times 4$

$60$

Therefore, 60 pens were broken.
