2) 522

Answer 2

Answer:

1) Let sugar crystal be 'x'

Here weight of sugar and number of sugar.

Crystals are in direct proportion.

2/9×10^6 = 5/X

X×2 = 5×9×10^6

X = (5×9×10^6)/2

X= (45 × 10^6)/2

X = 2.25×10^6

2) Let sugar crystal be 'x'

Here weight of sugar and number of sugar.

Crystals are in direct proportion.

2/9×10^6 = 1.2/X

X×2 = 1.2×9×10^6

X = (1.2×9×10^6)/2

X= (10.8× 10^6)/2

X = 5.4×10^6
