Answer:

let the cost of groundnuts per kg be x

and let the cost of cashews per kg be y

according to question :

15x +4y=7000. -(1)

10y=25x. -(2)

from equation (2)

y=25x/10

y=5x/2

put y =5x/2 in equation (1)

15x +4(5x/2)=7000

15x +10x =7000

25x=7000

x=7000/25

x=280

hence, the coat of groundnuts per kg is 280.
