Answer 2

Step-by-step explanation:

Let the cost of groundnut be X

the cost of cashew be Y

STEP:1 Given that 15X+4Y=7000

STEP:2. 10Y. =25X

2Y =5X

by using substitution method X=2Y/5

this value X is substitute in Step 1

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

3(2Y)+4Y. =7000

6Y+4Y. =7000

10Y=7000

Y=7000/10

Y=700

so cost of cashew is 700

cost of groundnut=2(700)/5

=2(140)

=280
