The total number of lollipops remains unchanged after Rael gives to Sam.
Total number of lollipops
= 350 + 619
= 969
Total number of lollipops in the end
= 1 u + 1 u + 59
= 2 u + 59
2 u + 59 = 969
2 u = 969 - 59
2 u = 910
1 u = 910 ÷ 2 = 455
Number of lollipops that Rael must give to Sam
= 619 - 455
= 164
Answer(s): 164
