Cheko and Keddy had the same amount of money initially. After Cheko donated $234 and Keddy donated $156 to charity, Keddy had 3 times as much as Cheko. How much had Keddy in the end?

At the start:     k + 156 = c + 234    (1)

At the end       k = 3c                      (2)

 

Put (2) into (1):     3c + 156 = c + 234

                             2c = 78

                              c = 39

so, from (3)           k = 3*39 = 117

 

Keddy had $117 in the end.
