Answer 1

Answer:

Step-by-step explanation:

Let X = Petrol price

    Y = Diesel price

    Z = Kerosene price

Question 1:

1X=3Y=5Z

Ratio:- X:Y:Z = 15:5:3

All three having equal volume.

So, amount spent on kerosene,

3/5*510 = 3*120 = 306Rs

So, option B. 306rs

Question 2:

Total amount =3* 510 + 510 + 306 = 2346Rs

Amount spent on Petrol and Kerosene = 15:3

Amount spent of Petrol = 15/18* 2346= 5/6 * 2346 = 1955Rs

So, option C.1955rs
