The total number of mochi balls remains unchanged after Valen gives to Ivan.
Total number of mochi balls
= 341 + 505
= 846
Total number of mochi balls in the end
= 1 u + 1 u + 52
= 2 u + 52
2 u + 52 = 846
2 u = 846 - 52
2 u = 794
1 u = 794 ÷ 2 = 397
Number of mochi balls that Valen must give to Ivan
= 505 - 397
= 108
Answer(s): 108
