Answer:
147
Explanation:
Given:
 Progesterone = 3.8 g 
Glycerin = 7 mL 
2% methylcellulose solution 50 mL 
Cherry syrup ad = 90 mL 
Now, 
The total volume of the solution = 7 + 50 + 90 = 147 mL
Also,
2% methylcellulose solution 50 mL is concluded as:
the volume of methylcellulose in the solution is 2% of the total volume of the solution
thus, 
volume of methylcellulose = 0.02 × 50 mL = 1 mL
Therefore, 
Ratio strength of methylcellulose in the finished product 
=

or
= 

Hence, the answer according to the question is 147
