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

### Instruction:
In a big box, there are marbles in 4 colors. Inside, there are 20 red marbles.  There are three times more green marbles than red.  Yellow marbles make up 20% of the green marbles. How many marbles are of a different color if the total of all marbles in the box is three times more than the number of green marbles?

### Response:
 Kuna mabulinge ya rangi ya kijani 3 * mabulinge ya rangi nyekundu 20 = <<3*20=60>>60.
Kuna mabulinge ya rangi ya manjano 60 * 20/100 = <<60*20/100=12>>12.
Jumla ya mabulinge ni 3 * 60 = <<3*60=180>>180.
Hivyo, kuna 180 - 20 - 60 - 12 = <<180-20-60-12=88>>88 mabulinge ya rangi tofauti katika sanduku.
