The solubility is 70 g/100 g water.
Explanation:
It appears that "they" are asking you to interpret a solubility curve like the one below.
(Adapted from Google Docs)
You draw a vertical line from 90 °C on the horizontal axis upward until it hits the curve for
Then, go horizontally from there until you reach the vertical axis.
The solubility is 70 g/100 g water.
