Answer:
Numbers of students at a primary school before= 240
Number of increased students =42
Again,
Increased number of students in percent(%)= 42/240×100%= 17.5%
Therefore 17.5% students are increased this year.
Answer:
18 minutes
Step-by-step explanation:
5 mins = 10 pages
10 mins = 20 pages
15 mins = 30 pages
20 mins = 40 pages
Just keep adding 5 to the minutes and 10 to the pages. then if you divide 10 by 5 (10÷5) you get 2.
2 is the amount of pages you read in 1 minute.
so 1 minute = 2 pages
Since you only need to read 36 pages, you know that it would at least take you 15 mintes to read 30.
then you start adding 1 minute until you get to 36 pages.
15 minutes = 30 pages
16 minutes = 32 pages
17 minutes = 34 pages
18 minutes = 36 pages
Therefore, it should take 18 minutes to read all 36 pages.
(A shorter way of doing this would be doing 10÷5=2, then just dividing 36 by 2 (36÷2) and you would get 18 which would be the minutes it would take you to read all 36 pages if you read at 2 pages per minute.)
