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

### Instruction:
Maria is baking cookies for Sally. Sally says that she wants 1/4 of her cookies to have nuts in them, 40% to have chocolate chips in them, and the remainder to have nuts and chocolate chips in them. When she adds nuts to the cookies, she uses 2 nuts per cookie. If she makes 60 cookies, how many nuts does she need?

### Response:
 35% ya biskuti zina karanga na vipande vya chokoleti kwa sababu 100 - 25 - 40 = <<100-25-40=35>>35
60% ya biskuti zina karanga tu kwa sababu 25 + 35 = <<25+35=60>>60
Idadi ya biskuti zenye karanga ni .60*60 = <<.60*60=36>>36
Anahitaji karanga 72 kwa sababu 36 x 2 = <<36*2=72>>72
