The total number of lollipops remains unchanged after Carl gives to Charlie.
Total number of lollipops
= 415 + 608
= 1023
Total number of lollipops in the end
= 1 u + 1 u + 53
= 2 u + 53
2 u + 53 = 1023
2 u = 1023 - 53
2 u = 970
1 u = 970 ÷ 2 = 485
Number of lollipops that Carl must give to Charlie
= 608 - 485
= 123
Answer(s): 123
