The total number of lollipops remains unchanged after Ivan gives to Ahmad.
Total number of lollipops
= 303 + 533
= 836
Total number of lollipops in the end
= 1 u + 1 u + 48
= 2 u + 48
2 u + 48 = 836
2 u = 836 - 48
2 u = 788
1 u = 788 ÷ 2 = 394
Number of lollipops that Ivan must give to Ahmad
= 533 - 394
= 139
Answer(s): 139
