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 much cloth will remain?

Answer 1

Length of cloth needed for stitching $1$ shirt$=2m15cm$

$=2m+15cm$

$=2\times 1m+15cm$

$=2\times 100cm+15cm$ (since $1m=100cm$)

Length of cloth needed for stitching $1$ shirt$=200+15=215cm$

Total length of cloth available$=40$m

since $1m=100cm$

Total length of cloth available$=40\times 100$cm

Total length of cloth available$=4000$cm

Total number of shirts can be made from available cloth

$=\frac{Totallengthofclothavailable}{Lengthofclothneededfor1shirt}$

Total number of shirts can be made from available cloth$=\frac{4000}{215}$

Quotient$=18$ and Remainder$=130$

$\therefore$ number of shirts that can be made$=18$

and remaining cloth$=130cm$

$=100cm+30cm$

since $1m=100cm$

Remaining cloth$=1m30cm$
