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

### Instruction:
Mr. Sergio is a fruit grower producing apples, mangoes and oranges. In a particular season, the total produce of apples was twice the total produce of mangoes, and the total produce of oranges was 200 kg more than that of mangoes. If his farm produced 400 kg of mangoes and he sold the fruits at $50 per kg,  calculate the total amount of money he got in that season.

### Response:
 Ikiwa Bwana Sergio alizalisha kilo 400 za maembe, uzalishaji wa machungwa ulikuwa kilo 400+200 = <<400+200=600>>600 za machungwa.
Jumla ya matunda yaliyozalishwa katika shamba la Bwana Sergio ni kilo 600 za machungwa + kilo 800 za maembe + kilo 400 za maembe = <<600+800+400=1800>>1800 za matunda.
Ikiwa aliouza matunda kwa $50 kwa kilo, jumla ya pesa alizopata kutokana na mauzo ya matunda ni $1800*50 = $<<1800*50=90000>>90000
