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

### Instruction:
 Lyssa na Precious walifanya mtihani wa uwezo wa Kiingereza. Lyssa alijibu 20% ya maswali vibaya. Precious alifanya makosa 12. Lyssa alipata majibu sahihi zaidi kwa idadi gani kuliko Precious ikiwa kulikuwa na maswali 75 katika mtihani?


### Response:
 Lyssa alipata 75 x 20/100 = <<75*20/100=15>>15 makosa.
Alama ya Lyssa ni 75 - 15 = <<75-15=60>>60.
Alama ya Precious ni 75 - 12 = <<75-12=63>>63.
Hivyo, Lyssa alipata majibu sahihi zaidi kwa 63 - 60 = <<63-60=3>>3 kuliko Precious.
