Method 1 :
(Volume of coke that Mr. Fei get) : (Volume of coke that Mr. Tai get)
= 156 : 117
= 4 : 3

Let 4k mL and 3k mL are the volumes of coke that Mr. Fei and Mr. Tai getrespectively.

3k = 450
k = 150

Total volume of the bottle of coke
= 4k + 3k mL
= 7k mL
= 7*150 mL
= 1050 mL


=====
Method 2 :
Total volume of the bottle of coke
= 450 * [(156 + 117)/117] mL
= 1050 mL
