Hint:

**Hint:**

In a proportional relationship, the variables are related by a constant ratio(k). For example, the equation which can relate the two variables can be written in the form:

y = (constant) x or y = k x.

So, for solving these types of questions we need to create a proportional relationship between the variables. These relationships can be direct, inverse etc.

## The correct answer is: Rs.1008.

### Step 1 of 2:

It is given that cost of 16 bags of washing powder, each weighing 1.5 kg, is Rs.672.

Total weight of washing powder that will cost Rs.672 = No. of bags Weight of each bag

= 16 1.5 = 24 kg

Cost of 1 kg of washing powder = = = 28

Step 2 of 2:

Now we are asked to find the cost of 18 bags of the same, each weighing 2 kg.

Total weight of washing washing powder = 2 18 = 36 kg

Total cost = Total weight Cost of 1 kg

= 36 28 = Rs.1008
