Answer 2

Answer:

Hence the cost of 3 kg rice is Rs.73.5

Step-by-step explanation:

As per the details proved in the above question,

It is given that cost of 10kg of rice is Rs.245

We have to find the cost of 10 kg rice,

We have to know the cost of 1 kg,

Cost of 1 kg rice is equal to cost of 10kg rice upon 10 we get,

$=\frac{245}{10} \\=Rs24.5$

The cost of 1 kg of rice is Rs24.5

The cost of 3 kg of rice is as bellow,

$=3\times 24.5$

Multiply 3 into 2 we get 6, 3 into 4 we get 12 and 3 into 5 we get 15.

$=Rs.73.5$

Hence the cost of 3 kg rice is Rs.73.5
