A field can be ploughed in 18 days. If everyday an additional area of ...
Let the area of the field ploughed daily be x hectares.
Area of the field = 18x
⇒ 18x = (x + 16) 12
⇒ 18x = 12x + 16 × 12
⇒ 6x = 16 × 12
⇒
Area of the field = 18 × 32 = 576 hectares
Area of the field = 18x
⇒ 18x = (x + 16) 12
⇒ 18x = 12x + 16 × 12
⇒ 6x = 16 × 12
⇒
Area of the field = 18 × 32 = 576 hectares

I don't think the answer option B.
I think the answer is None of these.
The correct answer should be 192.
They can plough 16 hectares each day.
They can plough that field in just 12 days.
Hence the calculation should be 192 because 16×12 is 192.
Please upvote to me and my answer if I am correct.

A field can be ploughed in 18 days. If everyday an additional area of ...
Let's assume the area of the field is x hectares.
First scenario:
In the first scenario, the field is ploughed in 18 days. This means that each day, 1/18th of the field is ploughed. Therefore, the daily ploughing rate is x/18 hectares.
Second scenario:
In the second scenario, each day an additional area of 16 hectares is ploughed. So, the daily ploughing rate in this scenario is (x/18) + 16 hectares.
Using the given information, we can set up the following equation:
12 * [(x/18) + 16] = x
Simplifying the equation:
12 * (x/18) + 12 * 16 = x
(2/3) * x + 192 = x
192 = x - (2/3) * x
192 = (1/3) * x
Solving for x:
x = 192 * 3
x = 576 hectares
Therefore, the area of the field is 576 hectares, which corresponds to option B.

Solving for x:
x = 192 * 3
x = 576 hectares
Therefore, the area of the field is 576 hectares, which corresponds to option B.
