The formerly 300ft fence would be 3000 inches. Since a foot is now 12 inches, the fence would be 3000/12 = 250ft.

The other way to calculate it is to take 300*10/12 (length*(old foot)/(new foot)).

Answer is A.

Solution



As the length of the foot increases from past to present, the original length should be less at present, compared to the past length of 300

Only one option is less than 300

Hence, the correct answer is option A.

Answer: A

Alternate (Conventional) Solution



Given:
    • Previously length of a foot = 10 inch
    • Presently length of a foot = 12 inch

To find:
    • What should be the length in present, of a former 300-foot fence

Approach and Working:
If we assume the present length of the former 300-foot fence is x, then we can write
    • 12 * x = 10 * 300
    Or, x = \(\frac{10 * 300}{12}\) = 250

Hence, the correct answer is option A.

Answer: A

Since the length of an inch remains constant, let’s convert the two “foot” systems to inches.

Now, since each old foot is 10 inches, 300 old feet = 300 x 10 = 3000 inches. Since each new foot is 12 inches, we see that 3000 inches = 3000/12 = 250 new feet.

Answer: A

Hi,
I did not get the question.
As well the solution.

What is the relation between king's foot and fence foot (only said that king's foot=length of foot) and also I did not get (Assume that the length of an inch remains constant.)
