You saw a shirt for Rs. 97

You didn’t have the cash, so you borrowed Rs. 50 from your Mom and Rs. 50 from you Dad

Rs. 50 + Rs 50 = Rs. 100

You bought the shirt, and had Rs. 3 change.

You gave your Dad Re 1 and your Mom Re 1 and kept the other Re 1 for yourself.

Now you owe your Mom Rs. 49 and you Dad Rs. 49

Rs. 49 + Rs. 49 = Rs. 98 + your Re 1 = 99

WHERE IS THE MISSING RE 1?
