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

### Instruction:
 George alikusanya mabulinge 50 ya rangi nyeupe, njano, kijani, na nyekundu. Nusu yao ni nyeupe, na 12 ni njano. Kuna mabulinge 50% chini ya mabulinge ya kijani kuliko mabulinge ya njano. Marbulinge mangapi ni nyekundu?


### Response:
 Nusu ya mabulinge ni nyeupe, hivyo kuna mabulinge 50 / 2 = <<50/2=25>>25 nyeupe.
Mabulinge ya kijani ni 50% tu ya mabulinge ya njano, hivyo kuna mabulinge 50/100 * 12 = <<50/100*12=6>>6 ya kijani.
Hivyo kwa sasa tunajua kuwa tuna jumla ya mabulinge 25 + 12 + 6 = <<25+12+6=43>>43.
Yaliyobaki ni nyekundu, hivyo kuna mabulinge 50 - 43 = <<50-43=7>>7 nyekundu.
