Number of green beads added

Number of green beads added to box A
      = (198/3) × 13 = 858
 

Total number of beads in box A (blue beads + green beads)
      = 858 + 198 = 1,056
 

Number of beads in box B (pink beads + yellow beads)
      = 1,056/4 = 264
 

Number of yellow beads added to box B
      = 264 - 219 = 45   ←   answer
