Suppose 2kg of sugar contains 9x10⁶

crystals. How Many sugar crystals are there in

1)5 kg of sugar
2) 1.2 kg of sugar​

Answer 1

crystal in 1kg sugar =(9×10⁶)/2 = 4.5×10⁶

crystals in 5kg sugar=5×4.5×10⁶=22.5×10⁶

crystals in 1.2 kg sugar=1.2×4.5×10⁶=5.4×10⁶

Answer 2

1)22.5× 10^6

2) 5.4× 10^6

Step-by-step explanation:

i) Given,

2 kgs of sugar contain 9×10

6 crystals

∴ 1 kg of sugar contain

2

9×10

6

crystals

and 5 kgs of sugar contain

2

9×10

6

×5 crystals

=2.25×10

7

crystals

ii) Again,

2 kgs of sugar contain 9×10

6

crystals

∴ 1 kg of sugar contain

2

9×10

6

crystals

and 1.2 kgs of sugar contain

2

9×10

6

×1.2 crystals

=5.4×10

6
