Answer 1

Answer:

Direct

Step-by-step explanation:

This is direct beacuse as no. of liters of oil will increase the price will also increase

Answer 2

The answer to your question could be:-

Given,

Amount of oil bought before = 24 liters

Cost of 24 liters of oil = 1200 Rupees

Amount of oil we need now = 18 liters

Cost of 18 liters of oil = ?

To find out the cost of 18 liters of oil, we first need to find the cost of 1 liter of oil which can be easily found by this -

Amount of oil = 24 liters

Cost of 24 liters of oil = 1200 Rupees

Cost of 1 liter of oil = 1200/24 = 600/12 = 300/6 = 150/3

                               = 50 Rupees

Now that we have the cost of 1 liter of oil, we multiple it by 18 because that's the amount of oil we need now -

Amount of oil we need now = 18 liters

Cost of 1 liter of oil = 50 Rupees

Cost of 18 liters of oil = 18 * 50

                                   = 900 Rupees.

If you are talking about inverse and direct proportions; then this would be a direct proportion because both values (1200 Rupees for 24 liters and 900 Rupees for 18 liters) depend on the same factor, as opposed to depending opposite factors which values in inverse proportions show.
