Answer: 0.06 litre or 60 ml

Step-by-step explanation:

Given: The capacity of glass tank= 26 liter

If he add 20.9 liters of water after 85 marbles to fill it completely, then

The volume of 85 marbles= $26-20.9=5.1\ liters$

Since, the marbles have same volume.

∴ Volume of each marble= $\frac{\text{volume of 85 marbles}}{\text{85}}$

⇒ Volume of each marble= $\frac{5.1\ litre}{85}=0.06\ liters$

In milliliters, Volume of each marble= $0.06\times1000=60ml$
