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

### Instruction:
In Mr. Bolton's class of 25 students, 2/5 of the students like maths, 1/3 of the remaining students like science, and the rest of the students like history. Calculate the combined total number of students who like history and those who like maths.

### Response:
 Ikiwa kuna wanafunzi 25 katika darasa, basi 2/5*25 = <<2/5*25=10>>10 wanafunzi wanapenda hesabu.
Idadi ya wanafunzi ambao hawapendi hesabu ni 25-10 = <<25-10=15>>15 wanafunzi.
Ikiwa 1/3 ya wanafunzi ambao hawapendi hesabu wanapenda sayansi, basi 1/3*15 = <<1/3*15=5>>5 wanafunzi wanapenda sayansi.
Idadi jumla ya wanafunzi wanaopenda sayansi na hesabu ni 5+10 = <<5+10=15>>15
Idadi ya wanafunzi ambao hawapendi wala hesabu wala sayansi ni 15-5 = <<15-5=10>>10
Kwa kuwa wanafunzi wengine wanapenda historia, basi 10-5 = <<10-5=5>>5 wanafunzi wanapenda historia.
Jumla ya wanafunzi wanaopenda historia na hesabu ni 5+15 = <<5+15=20>>20
