Question

Ishika was asked by her teacher to measure the length of the line drawn on the blackboard. She immediately took out her scale to measure the line. But she noticed that the end of her scale was broken. She felt very sad and said to the teacher that she would not be able to measure the length of the line. Teacher consoled her and taught her a new method of measuring line using the same scale.
What new method of measuring the length of the line by using a broken scale was taught by Ishika’s teacher?

Answer 1

Answer:

Ishika's scale was broken and was taught a new way to measure length with a broken scale.

Explanation:

Let's see what the new method is:

Let's assume the reading on the scale is visible only beyond 2cm. The initial 1cm is broken.

Now, Ishika is supposed to measure the line putting the starting point at 2cm . let's say the measurement came to be 10 cm.

But we know that the measurement begun from 2 cm.

Thus, to find the actual length of the line, 2cm will be subtracted from 10 cm

This will make the actual length of the line to be 8cm.

This is the new method of measuring length with a broken scale.

Hope it helps!
