@All.

True * true = wrong * wrong.
500 * 20=502 * wrong length of tape,
So, after calculation, it is 19.92 that is A is the correct answer.

It measures more than the actual length. Only possible when the tape is short.

Tap = 500x20/502.
= 19.92 m (correct Chain length).

500x20/502 = 19.92.

A is correct.

True*True = False*False
20*500 = 502*l
L = 19.92m.

X/20 = 500/502.
X = 500/502*20 = 19.92m.

The answer is A.

500y = 502x20.

y = 502x20/500.

y = 20.08.
