To stitch a trouser, 1 m 30 cm cloth is needed. Out of 25 m cloth, how many trousers can be stitched and how much cloth will remain?

Length of cloth available = 25 m

= (25 × 100) cm

= 2,500 cm

Length of cloth required to stitch a trouser = 1 m 30 cm

= (1 × 100 + 30) cm

= 130 cm

Dividing 2,500 by 130:

Quotient = 19, remainder = 30.

So, 19 trousers can be stitched and 30 cm of cloth will remain.

Hence, the number of trousers that can be stitched is 19 and the length of the remaining cloth is 30 cm.
