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 math test, Mark scored twice as much as the least score. If the highest score is 98 and the range of the scores is 75, what was Mark's score?

### Response:
 Tofauti ya alama inamaanisha tofauti kati ya alama ya juu na alama ya chini hivyo 75 = 98 - alama ya chini
Kwa hiyo, alama ya chini = 98 - 75
Alama ya chini ni 23
Mark alipata mara mbili ya alama ya chini ambayo ni 2 * 23 = <<2*23=46>>46
