​

Answer 1

Answer:

Rs. 6750

Step-by-step explanation:

As per the provided information in the given question, we have :

• Amount of petrol consumed in going from town A to B = 40 litres
• Amount of petrol consumed in going from town B to C = 50 litres
• Cost of petrol per litre = Rs. 75

We are asked to calculate the total amount spent on petrol.

In order to calculate total amount spent on petrol, firstly we need to find the total amount of petrol which have been used by the car. From town A to B, it consumes 40 litres of petrol and then from B to C, it consumes 50 litres of petrol. Thus, sum of the amount of petrol consumed in going from town A to B and from town B to C is the total amount of petrol which have been used by the car.

$\longmapsto\rm {Petrol's \; amount_{(Total)} = (50 + 40) \; \ell }$

Add both the values, i.e 50 and 40.

$\longmapsto\rm {Petrol's \; amount_{(Total)} = 90 \; \ell }$

Now, in the question we've been given that the cost of 1 litre of petrol is Rs. 75. So, the total amount spent on the petrol will be the product of the amount of petrol used and cost of 1 litre of petrol. That is,

$\longmapsto\rm {Cost_{(Total)} = Cost_{(1 \; \ell)} \times Amount_{(Petrol)} }$

Substitute the values.

$\longmapsto\rm {Cost_{(Total)} = Rs. \; (75 \times 90) }$

Multiplying 75 with 90.

$\longmapsto\bf {Cost_{(Total)} = Rs. \; 6750 }$

∴ The total amount spent on petrol is Rs. 6750.
