Neha takes 5 hours to type 40 pages while sunil takes 6 hours to type ...
In one hour number of pages type by neha = 40/5 = 8 and similarly for sunil it is 60/6 = 10.
Now to type 180 pages they will take, (8 + 10)*T = 180, T = 10 hours
Now to type 180 pages they will take, (8 + 10)*T = 180, T = 10 hours

Neha takes 5 hours to type 40 pages while sunil takes 6 hours to type ...
Given information:
- Neha takes 5 hours to type 40 pages.
- Sunil takes 6 hours to type 60 pages.
To find:
- How much time will they take working together on different computers to type an assignment of 180 pages?
Let's calculate the typing rates of Neha and Sunil first.
Neha's typing rate:
- Neha takes 5 hours to type 40 pages.
- Therefore, Neha's typing rate is 40 pages / 5 hours = 8 pages per hour.
Sunil's typing rate:
- Sunil takes 6 hours to type 60 pages.
- Therefore, Sunil's typing rate is 60 pages / 6 hours = 10 pages per hour.
Now, let's calculate the total time they will take working together.
Total pages to be typed = 180 pages
Let's assume they take 'x' hours to complete the assignment together.
Neha's contribution in 'x' hours:
- Neha's typing rate is 8 pages per hour.
- Therefore, Neha will type 8 * x pages in 'x' hours.
Sunil's contribution in 'x' hours:
- Sunil's typing rate is 10 pages per hour.
- Therefore, Sunil will type 10 * x pages in 'x' hours.
Total pages typed in 'x' hours = Neha's contribution + Sunil's contribution
= (8 * x) + (10 * x)
= 18 * x pages
According to the given information, the total pages to be typed is 180 pages.
Therefore, 18 * x = 180
Solving for 'x':
18 * x = 180
Divide both sides by 18: x = 180 / 18
x = 10
Therefore, they will take 10 hours to complete the assignment together.
Answer: Option E) None of these.
- Neha takes 5 hours to type 40 pages.
- Sunil takes 6 hours to type 60 pages.
To find:
- How much time will they take working together on different computers to type an assignment of 180 pages?
Let's calculate the typing rates of Neha and Sunil first.
Neha's typing rate:
- Neha takes 5 hours to type 40 pages.
- Therefore, Neha's typing rate is 40 pages / 5 hours = 8 pages per hour.
Sunil's typing rate:
- Sunil takes 6 hours to type 60 pages.
- Therefore, Sunil's typing rate is 60 pages / 6 hours = 10 pages per hour.
Now, let's calculate the total time they will take working together.
Total pages to be typed = 180 pages
Let's assume they take 'x' hours to complete the assignment together.
Neha's contribution in 'x' hours:
- Neha's typing rate is 8 pages per hour.
- Therefore, Neha will type 8 * x pages in 'x' hours.
Sunil's contribution in 'x' hours:
- Sunil's typing rate is 10 pages per hour.
- Therefore, Sunil will type 10 * x pages in 'x' hours.
Total pages typed in 'x' hours = Neha's contribution + Sunil's contribution
= (8 * x) + (10 * x)
= 18 * x pages
According to the given information, the total pages to be typed is 180 pages.
Therefore, 18 * x = 180
Solving for 'x':
18 * x = 180
Divide both sides by 18: x = 180 / 18
x = 10
Therefore, they will take 10 hours to complete the assignment together.
Answer: Option E) None of these.
