Answer:
It will take <u>3 hours</u> for 5 examiners to mark 80 papers.
Step-by-step explanation:
Given:
Time taken by an examiner to mark 80 exam papers = 15 hours
To find time taken by 5 examiners to mark 80 exam papers.
Solution:
Applying unitary method.
One examiner takes 15 hours to mark 80 exam papers
So, in one hour he can mark = papers
In hour 5 examiners can mark = papers
So, we know 5 examiners can mark papers in 1 hours.
So, to mark 1 paper they will take = = of a paper
Thus, to mark 80 papers they will take = hours.
Thus, it will take 3 hours for 5 examiners to mark 80 papers.
Answer: There are 37 students in the drama club and 27 students in the drama club.
Step-by-step explanation:
Let x= number of students in the drama club.
y= number of students in the yearbook club.
As per given, we have
x+y=64
x=10+y
A system of linear equations that represents this situation:
x+y=64 (i)
x=10+y (ii)
Put value of x from (ii) in (i)
10+y+y=64
⇒ 2y= 54
⇒ y = 27 [Divide both sides by 2]
Put value of y in (ii) , we get
x= 10+27 = 37
Hence, there are 37 students in the drama club and 27 students in the drama club.
