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?

We know, 1 m = 100cm

Therefore, 2 m 15 cm = 215cm

40 m = 40×100 cm = 4000 cm

Now the cloth required for one shirt = 215 cm

Number of shirts that can be stitched out of the 4000cm = 4000÷215

Therefore, 18 shirts can be made from 4000cm long cloth. Out of 4000 cm, 130cm cloth will remain which is 1m 30cm.
