Question

Petrol and kerosene mixture in a ratio 7:14 . Total volume of mixture is 500 liters .Find the compostion of petrol in overall mixture

Answer 1

Answer:

Step-by-step explanation:

Let the composition be 7x and 14x.

Then, 7x + 14x = 500

        21x = 500

         x = 500/21

         x = 23.809523

therefore, 7x = 7 x 23.809523 = 166.666661 = 166.7

               14x = 14 x 23.809523 = 333.333322 = 333.3

therefore , 166.7 + 333.3 = 500

Volume of Petrol = 166.7 L

Volume of Kerosene = 333.3 L
