Question

to stitch is shirt 2 metre 15 CM cloth is needed out of 40 cloth, how many shirt can be stitched and how much cloth will remain maths sum

Answer 1

2 m 15 cm per shirt
40 m cloth

1 m = 100 cm

2m * 100cm/m = 2 * 100cm = 200 cm
200 cm + 15 cm = 215 cm per shirt

40 m * 100cm/m = 40 * 100cm = 4,000 cm
4,000 cm / 215cm = 18.60

18 shirts can be made.

215 cm * 18 = 3870 cm
4,000 - 3,870 = 130 cm cloth left.

Answer 2

Total cloth needed to stitch a shirt= 2 m 15 cm
Total Cloth=40 m
1 m= 100 cm
so 2 m 15 cm =2×100+15 cm=215 cm
and 40 m=40×100=4000cm
Total shirts can be stitched= Total cloth/ Total Cloth Needed
                                          = 4000/215
                                          = 18 shirts (approx.)
