QUESTION

# To stitch a shirt 2 m 15 cm cloth is needed. Out of 40 m cloth, how many shirts can be stitched and how many clothes will remain?

Hint: Total numbers of shirts that can be made from the available cloth will be the ratio of total length of cloth available in cm and the length of cloth needed for 1 shirt in cm. Therefore we will convert both the quantities in cm and then proceed further to find the cloth by the remainder.

Total length of cloth available = $40 \times 100{\text{ cm}}$
$= \dfrac{{{\text{Total length of cloth available}}}}{{{\text{Length of cloth needed for 1 shirt}}}} \\ = \dfrac{{4000}}{{215}} \\ = 18 + \dfrac{{130}}{{215}} \\$
$= 100 + 30 \\ = 1{\text{ m 30 cm }}\left[ {{\text{since 1 m = 100 cm}}} \right] \\$
