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

### Instruction:
Georgia is working on a math test with 75 problems on it. After 20 minutes she has completed 10 problems. After another 20 minutes, she has completed twice as many problems. She has 40 minutes to complete the rest of the test. How many problems does she have left to solve?

### Response:
 Anamaliza maswali 10 kwa dakika 20, hivyo anamaliza maswali 10 / 20 dakika = <<10/20=.5>>.5 dakika kwa swali.
Katika dakika nyingine 20 anamaliza maswali mara mbili ya hapo awali, hivyo 10 x 2 = <<10*2=20>>20 maswali.
Anamaliza maswali 10 kwa dakika 20, hivyo ni .5 dakika kwa swali. Kukamilisha maswali 20 anachukua 20 x .5 = <<20*.5=10>>10 dakika.
Kwa dakika 40 zilizobaki, anasuluhisha maswali 10 + 20 = <<10+20=30>>30.
Ana maswali 75 kwenye mtihani na amesuluhisha 30, hivyo ana maswali 75 - 30 = <<75-30=45>>45 yaliyobaki.
