cost of 5 kg = 30.50

cost of one kg = 30.50/5

cost of 1kg = ₹6.1

To find Cost of 9 kg of wheat we need to first find cost of 1 kg of wheat and then multiply it by 9.

Cost of 5 kg wheat =Rs 30.50

∴Cost of 1 kg wheat=Rs30.50/5=Rs6.1

Now,

Cost of 9 kg of wheat=9×Cost of 1 kg of wheat

                                   =Rs 9×6.1

                                   =Rs54.9 ≅Rs55(approximately)

∴Cost of 9 kg of wheat is Rs 55.
