Question

एक 8 मीटर लम्बे तथा 1 मीटर 50 से.मी. चौड़े कपड़े के थान से 40 से.मी. भुजा वाले कितने रुमाल बनाये जा सकते हैं?​

Answer 1

Answer:

20 hankies. - cloth 8m l 1.5cm b

a/q 1m - 100cm

8m - 800cm

800÷40 = 20 hankies.

Answer 2

Given:

Length = 8 meter and breadth = 1 meter and 50 nm

Solution:

Know that, $\[1\,{\rm{m}} = 100{\rm{ cm}}\]$

Therefore,$\[8\,{\rm{m}} = 800{\rm{ cm}}\,\,{\rm{and 1m}}\,\,{\rm{50cm = 150 cm}}\]$

Understand that 150 is not completely divisible by 40, so that take a number less than 150 that should be divisible by 40 i.e. 120

Calculate the total number of handkerchiefs,

$\[ = \frac{{800}}{{40}} \times \frac{{120}}{{40}}\]$

$\[\begin{array}{l} = 20 \times 3\\ = 60\end{array}\]$

Hence the total number of handkerchiefs made from the given clothe is 60.
