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

Answer:

Total cloth \[=40\text{ }m\] \[\text{=(40}\times \text{100) }cm,\] as \[\text{ }1\text{ }m=100\text{ }cm\] \[=4000\text{ }cm\]                                                                                                                               Cloth needed for 1 shirt \[=2\text{ }m\text{ }15\text{ }cm\] \[=2\text{ }m+15\text{ }cm\] \[=(2\times 100)\text{ }cm+15\text{ }cm\] \[=(200+15)\text{ }cm\] \[=215\text{ }cm\]                                                                                                                                 Number of shirts stitched out of total cloth \[=4000\div 215\] Now,                                                                                                                                            \[\therefore \] 18 shirts can be stitched and cloth left over is 130 cm i.e., 1 m 30 cm.
