The amount of sugar in kg -3

4

Number of crystals

9x10^8

х

So, this two quantities are in directly proportional

Therefore

X1/y1 = x2/y2

= 3/9x10^8 = 4/x

=3xx =4x9x10^8

Therefore,

X=4x9x10^8/3 =12x10^8 = 1.2x10^9

So, the answer is 12x10^8 or 1.2x10^9

No.of crystals are there in 4 kg is 1.2x10^9
