The correct option is
B ₹9.08
Total amount of money left with John = ₹50
Cost of each notebook = ₹11.24
Cost of 2 notebooks = 2 × ₹11.24
So, cost of 2 notebooks = ₹22.48
Cost of each pen = ₹6.48
Cost of 3 pens = ₹6.48 × 3
So, cost of 3 pens = ₹19.44
Total cost of 2 notebooks and 3 pens = ₹22.48 + ₹19.44
So, cost of 2 notebooks and 3 pens is ₹41.92
Amount of money left with John = ₹50 - ₹41.92
Thus, the amount of money left with John is ₹9.08
