Answer 2

Step-by-step explanation:

let the cost of one apple be x

and the cost of one mango is y.

According to question-

5x+4y=36                                              eq.1

7x+8y=48                                              eq.2

on multiplying eq.1 by 2 and eq.2 by 1 then we get

10x+8y=72                                              eq.3

7x+8y=48                                               eq.4

on subtracting eq.4 from eq.3 we get

3x=24

x=8

putiing the value of x in eq.1

5*8+8y=36

40+8y=36

8y= -4

y=-1/2

Therefore, the cost of one apple is 8 and the cost of mango is 1/2.
