If a Quarter Kg of Potato Costs 60 Paise, How Many Paise will 200 gm Cost?

  • If a quarter Kg of potato costs 60 paise.
  • The cost of 200 gm potatoes can be figure out in this way.

Explanation

Two given entities here are

  1. Potatoes
  2. Cost

To determine the relation here, let suppose; cost of 200 gm potatoes = y

Case

As we know that;

1 Kg = 1000 gm

1/4 Kg = 250 gm

Potatoes               Cost

250                      60

200                      y

  • More potatoes means more price.
  • Small quantity of potatoes would require less price.

This clearly indicates that there is direct relation.

Direct/Indirect relation tells how the equation will be written.

250 : 200  ::  60 : y ________ (A)

After simplifying equation (A), we can easily figure out the value of y (y = 48 paise)

To Find

Cost of 200 gm potatoes = y

Solution

Method I

Let suppose

Cost of 200 gm potatoes = y

Potatoes              Cost

250                      60

200                      y

Relation between mangoes and price is direct, so;

250 : 200  ::  60 : y

250 x y = 200 x 60

y = 12000/250

y = 48 paise

Cost of 200 gm potatoes = 48 paise answer

Method II

Cost of 250 gm potatoes = 60 paise

Cost of 1 gm potatoes = 60/250

Cost of 1 gm potatoes = 0.24 paise

Cost of 200 gm potatoes = 0.24 x 200

Cost of 200 gm potatoes = 48 paise

Cost of 200 gm potatoes = 48 paise answer

Conclusion

If a quarter Kg of potato costs 60 paise, the cost of 200 gm potatoes would be 48 paise.
