Answer 2

$\bold{\underline {\red{Method \:1}}}$

$\bold{\underline{\underline {Given\:}}}$

• A book contains 160 pages in it.
• 15% pages have pictures on them.

$\bold{\underline{\underline {Find\:}}}$

Number of pages that don't have pictures on them.

$\bold{\underline{\underline {Solution\:}}}$

We have given in question that a book contains 160 pages.

Total pages in a book = 160

Also, 15% pages contains pictures on them.

So,

=> 15/100

We have to find that how many pages don't contain any pictures.

Now,

The number of pages that contain pictures..

=> 160 × (15/100)

=> 160 × 0.15

=> 24 pages

From above calculations we have 24 pages that contains pictures on them.

Pages that do not have any pictures = Total number of pages - Pages that have pictures

Substitute the known values in above formula

=> 160 - 24

=> 136 pages

•°• 136 pages have no pictures on them.

$\bold{\underline {\red{Method \:2}}}$

15% of pages have pictures on them.

So,

Percentage of pages without pictures = (100 - 15)%

=> 85%

Total number of pages = 160

So,

Pages that do not have any pictures = 160 × (85/100)

=> 160 × 0.85

=> 136 pages

•°• 136 pages do not have any pictures on them.
