Internal transfer, so the total amt of $ will not change in both cases. Hence, make the units of the Total to be the same😊 C1: S gave J $17 S : J : Total 4 : 7 : 11 8: 14 : 22 C2: S gave J $5 S : J : Total 1 : 1 : 2 11 : 11 : 22 Since we are looking for Sumei, let's form equations using Sumei's original in both cases. 8u+ 17 = 11u + 5 3u= 17 - 5 = 12 1u= 4 Using C1, 8u+17= 49 (ans)
