Question 9.
To stitch a shirt, 2 ml5 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:
2m 15cm = 215 cm( 1 m = 100 cm)
40m = 40 × 100
= 4000 cm
cloth required for one shirt = 215 cm
Number of shirt that can be stitched out of 4000 cm = 4000 ÷ 215
therefore, is shirts can be made 130 cm, i,e, 1 m 30 cm, cloth will remain.
Question 10.
Medicine is packed in boxes, each weighing 4 kg 500g. How many such boxes can be loaded in a van which cannot carry beyond 800 kg?

800 kg = 80 × 1000 = 800000 g
Number of boxes that can loaded in the van = 800000 ÷ 4500 = 800 ÷ 4.5
Hence, 117 boxes at maximum can be loaded in the van
