10 Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be
Answers
Step-by-step explanation:
Cloth required to stitch one shirt= 2 m 15cm = 2 x 100 cm + 15cm = 215 cm
Length of cloth = 40 m = 40 × 100 cm = 4000 cm
Number of shirts can be stitched = 4000/215 = 18.6
But we cannot consider number of shirts in decimals.
Therefore, 18 shirts can be stitched and 130 cm (1 m 30 cm) cloth will remain.
