        B   :    C               A   :    B

      150 :   100          80    :    100

       3    :     2              4    :    5

×5   |          |×5     ×3 |         |×3

      15   :    10            12       15

A  = 36

12u = 36

1u = 36 ÷ 12

      = 3

A+B+C –> 12u + 15u +10u

             = 37u
