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

### Instruction:
Meryll wants to write 35 multiple-choice questions and 15 problem-solving questions for her Chemistry class. She already has written 2/5 of the multiple-choice and 1/3 of the problem-solving questions. How many more questions does she need to write for both multiple-choice and problem-solving?

### Response:
 Kuchagua: maswali 35 x 2/5 = maswali 14.
Kutatua matatizo: maswali 15 x 1/3 = maswali 5.
Yaliyoandikwa: maswali 14 + maswali 5 = <<14+5=19>>maswali 19.
Maswali 35 + maswali 15 = <<35+15=50>>maswali 50.
Meryll anahitaji kuandika maswali 50 - maswali 19 = <<50-19=31>>maswali 31 zaidi.
