Answer 2

Given:

Rahul has a novel which has 160 pages and his younger brother tore 15 % of pages

To find:

How many pages were left in novel

Solution:

15 % can be represent as $\sf \dfrac{15}{100}$

ATQ,

Novel contains 160 pages

∴$\sf \dfrac{15}{100}$ ×160

∴$\sf \dfrac{15}{10}$ ×16

∴$\sf \dfrac{15}{5}$ ×8

∴$\sf \dfrac{3}{1}$ ×8

∴$\sf{3×8}$

∴$\sf \pink{24 \ pages}$

Now pages left= 160-24

∴Total pages left=$\sf \pink{136 \ pages}$

Hence, $\sf \pink{136}$ pages are left in novel..
