Given that the 2kg Potatoes =Rs.36
So, the 1kg Potatoes =362=Rs.18
Since, Madhu buys 5kg Potatoes =18×5=Rs.90.
Hence, Madhu will pay Rs.90.
Hence, this is the answer.
The price of 1kg of potato is Rs. 60. 1 kg onions cost 10% less than 1 kg potato. If I pay Rs. 180 for potatoes, what will be the cost of onions (of the weight same as the weight of the potatoes)?
