Question

12 cashews and 13 pears cost Rs 43.50, while 8 cashews and 17 pears cost Rs 41.50. How much will 6 cashews and 9 pears cost?​

Answer 1

Cost of 1 cashew= Rs. 2

Cost of 1 pear = Rs. 1.5

6×2+9×1.5= 12+13.5= Rs. 25.5

Let cost of 1 cashew = Rs.x

Cost of 1 pear = Rs.y

12x+13y= 43.50 (×2)

24x+26y= 87

8x+17y= 41.50 (×3)

24x+51y= 124.50

By elimination

25y= 37.50

y= Rs. 1.5

x= Rs. 2
