Assuming you saw a loptop of 97k. You didn't have the cash, so you borrowed 50k from ur mum & 50k from ur Dad= 100k. U bought the laptop which Left u with 3k change. U gave ur mum 1k & ur Dad 1k & kept the other 1k to urself. Now, u own ur mum 49k & ur Dad 49k = 49k+49k = 98k + ur 1k kept = 99k. Where is the missing 1k. Is there a mathematician in the house. If yes, solve it for me. Please
