    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
