Below is an instruction that describes a task. Write a response that appropriately completes the request in Swahili. Please answer in Swahili.

### Instruction:
Carolyn buys a silverware set with 6 knives, 12 forks, and three times as many spoons as knives. Then her friend trades her 10 knives for 6 spoons. What percentage of Carolyn's silverware is knives?

### Response:
 Kwanza tafuta idadi ya visu ya mwisho ambayo Carolyn anayo: visu 10 + visu 6 = <<10+6=16>>16 visu
Kisha tafuta idadi ya awali ya vijiko ambayo Carolyn anayo: visu 6 * vijiko 3/visu = <<6*3=18>>18 vijiko
Kisha tafuta idadi ya vijiko ya mwisho ambayo Carolyn anayo: vijiko 18 - vijiko 6 = <<18-6=12>>12 vijiko
Kisha ongeza idadi ya kila aina ya vyombo vya chakula ambavyo Carolyn anayo ili kupata jumla: vijiko 12 + visu 16 + uma 12 = <<12+16+12=40>>40 vipande vya vyombo vya chakula
Kisha gawanya idadi ya visu na jumla ya vipande vya vyombo vya chakula na kuzidisha na 100% ili kuonyesha jibu kama asilimia: visu 16 / vipande 40 * 100% = 40%
