Answer 2

let the cost of apples per kg be x
and the cost of pear per kg be y

acc. to ques
8x + 7y = 1060

and 4y=3x so x = 4y/3

8(4y/3) + 7y = 1060

32y/3 + 7y =1060

(32y +21y)/3 =1060
53y= 3180
y= 60 i.e the cost of pear per kg

but 4y = 3x
so 240 = 3x
x = 240/3
so x = 80 i.e cost of apple per kg
