Answer 1

Given -

• Total pages in novel is 900 pages.

• She read on Friday is 250 pages.

• She read on Sunday is 60% of remaining pages.

• On Monday she read 104 pages.

To Find -

• Percentage of remaining pages after Monday.

Solution -

Total number of pages in book = 900 .

Firstly let's find the number of pages read by Richi on Sunday.

Pages read on Sunday = 60% of pages left after Friday's reading .

Pages left after Friday's reading = 900 - 250.

→ 650 pages left .

Now we have to find 60% of 650.

$\boxed {\boxed{ \sf{ \red{ \implies \: \frac{percentage \: \times total \: number}{100} }}}}$

$\sf{ \implies \: \frac{60 \: \times 650}{100} }$

$\sf{ \implies \: \frac{\cancel{60} \: \times \cancel{650}}{\cancel{100}} }$

$\sf{ \implies \: 6 \times 65 = 390 }$

So, Richi read 390 pages on Sunday .

Now let's find total pages rate by Richie till Monday.

→ Pages read on [ Friday+Sunday+Monday]

$\sf{ \implies \: 250 + 390 + 104 = 744. }$

Now remaining pages in the novel -

→ Total pages - pages read by Richie.

$\sf{ \implies \: 900 - 744 = 156 }$

Pages left in Richie's novel is 156 .

Now let's convert it into percentage form .

$\sf{ \implies \: \frac{156}{900} \times 100 }$

$\sf{ \implies \: \frac{15600}{900}}$

$\underline{\underline{\sf{\red{ \implies \: 17 . 34 \: percent }}}}$

Answer 2

Question :–

• There are 900 pages in a novel. Richi reads 250 pages of the novel on Friday and 60% of the remaining pages on Sunday. Then she reads 104 pages more on Monday. Express the number of pages that remains to be read as a percentage of the total number of pages in the novel.

ANSWER :–

GIVEN :–

• Total page in novel = 900

• she read 250 pages on Friday.

• She read 60% of remaining pages on sunday.

• She read 104 page on Monday.

TO FIND :–

• Remaining pages in percentage after Monday.

SOLUTION :–

• According to the first condition –

=> Total pages = 900

• According to the second condition –

=> She read 250 pages on Friday.

=> So that remain pages = 900 – 250 = 650

• According to the third condition –

=> She read 60% of remaining pages on sunday.

=> So that , She read on sunday = 60 % of 650

=> She read on sunday = (650 × 60)/100

=> She read on sunday = 65 × 6 = 390

• According to the fourth condition –

=> She read 104 page on Monday.

• So that , Total readed pages = 250 + 390 + 104 = 744

• Hence, Total remaining pages = 900 - 744 = 156

• Now Let's convert in percentage –

= [156/900] × 100

= 156/9

= 17.34 %

• Hence , 17.34 % pages will remain after Monday.
