8 F + 14 O = 36520

Dividing the equation by 2 on both sides

4 F = 7 O = 18260

Given The cost of 8 fans and 14 ovens is rs 36520 find the cost of 12 fans and 21 ovens.

Let the equation for the cost of 8 fans and 14 ovens be

             8 f + 14 v = 36520

here we have to get 12 and 21 in the equation, so first divide the equation by 2 and then multiply the equation by 3.

  By dividing we get 4 f + 7 v = 18,260

Now multiplying by 3 we get

                          12 f + 21 v = 54,780

hence the cost of 12 fans and 21 ovens is Rs 54,780
