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?

0.99 x 200 ==198 kg - water by weight

200 - 198 ==2 kg - fruit by weight.

After drying up in the sun for two days, we have:

90% - water by weight

10% - fruit by weight

B ==weight of the berries

But fruit by weight ==2 kg. Therefore, we have:

10%B ==2 kg

0.10B == 2

**B == 2 / 0.10 ==20 kg - weight of the berries after 2 days in the sun.**
