In a store window, there was a box of berries having a total weight of 200 kg.  The berries were 99% water, by weight.  After two days in the sun, the water content of the berries was only 90%, by weight.  What was the total weight of the berries after two days, in kg?

1% x 200 = 2

so 2kg of berries did not change.

198kg were water.

10% of the water were gone.

10% x 200 = 20

That means now 178kg were now water

So 178+2 = 180
