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? (Hint: convert data in cm.)
Solution:
We will be using the concept of whole numbers and unit conversion to solve the given problem.
Total length of the cloth = 40 m
On converting it to cm we get 40 × 100 cm = 4000 cm
Length of cloth required to stitch one shirt = 2 m 15 cm = 2 × 100 + 15 cm = 215 cm
Number of shirts that can be stitched in total using 40 m cloth = Total length of the cloth / Length of cloth required to stitch one shirt
⇒ 4000 / 215 ≈ 18 shirts
Thus, a total of 18 shirts can be stitched out of 40 m.
Length of the cloth remaining after stitching 18 shirts = Total length of the cloth - 18 × Length of cloth required to stitch one shirt
⇒ 4000 - 18 × 215
⇒ 130 cm = 1m 30cm
Thus, the remaining cloth is of the length 1m 30cm.
