Step-by-step explanation:

As per the details proved in the above question,

It is given that cost of 2kg of rice is Rs.70

We have to find the cost of 7 kg rice,

We have to know the cost of 1 kg,

Cost of 1 kg rice is equal to cost of 2kg rice upon 2 we get,

$=\frac{70}{2} \\=Rs35$

The cost of 1 kg of rice is Rs.35

The cost of 7 kg of rice is as bellow,

$=7\times 35$

Multiply 7 into 5 we get 35 and 7 into 3 we get 18.

$=Rs.245$

Hence the cost of 7 kg rice is Rs.245
