Answer:

Hence the cost of 18 kg rice is Rs.756

Step-by-step explanation:

As per the details proved in the above question,

It is given that cost of 7kg of rice is $.294

We have to find the cost of 18 kg rice,

We have to know the cost of 1 kg,

Cost of 1 kg rice is equal to cost of 7kg rice upon 7 we get,

$=\frac{294}{7} \\=Rs42$

The cost of 1 kg of rice is Rs.42

The cost of 18 kg of rice is as bellow,

$=18\times 42$

Multiply 8 into 2 we get 16, 1 into 2 we get 2 ,

4 into 8 we get 42, and 1 into 4 we get 4.

$=Rs.756$

Hence the cost of 18 kg rice is Rs.756
