Solution
The correct option is A ₹10 Quantity of hair clip = 6
Quantity of hair pin = 4
Now, their quantity is getting interchanged,
Quantity of hair clip = 4
Quantity of hair pin = 6
Original total = ₹216
Final total = 4*15 + 6*10 + 3*12 + 2*25 = ₹206
Change in the value of bill = ₹216 - ₹206 = ₹10
(C) is the correct answer.
