= 1 kg 250 g
Question no – (9)
Solution :
5 L = 5000 ml
No. Bottles need to be filled
= 5000/250
= 20
Question no – (10)
Solution :
No. of drums will be filled
= 100/10
= 10

8 m 64 cm = 864 cm
Length of each strip = 864/4
= 216 cm
= 2 m 16 cm
Question no – (12)
Solution :
20 kg 250 g = 26,250 g
1 week = 7 day
∴ Flour is used in a day
= 26250/7
= 3750g
= 3kg 750g
Question no – (13)
Solution :
21 km 200 m = 21200m
He walk in a day = 21200/4
= 5300 m
= 5 km 3m
∴ He walk in 5 day –
= 5 × 5300 m
= 26500 m
