Question

A generator consumes 2.875 L of diesel per hour. The quantity of diesel required to run the generator for 24 hours is?
A) $45L$
B) $55L$
C) $72L$
D) $62L$

Answer 1

Hint:Here, quantity of diesel is given which a generator consumes in 1 hour and quantity of diesel which the generator requires for 24 hours can simply be obtained by multiplication & that product will be the answer to this problem.
Basically, formula applied here is $$-Dieselconsumedperhour\times No.ofhoursinaday.$$

Complete step-by-step answer:
Given, generator consumes diesel per hour $=2.875Litres$
To find the quantity of the diesel consumed by the generator we use the formula
$$TotalDieselConsumed=Dieselconsumedperhour\times No.ofhoursinaday.$$
Now we put the value in the formula for getting quantity of diesel required to run the generator for 24 hours we get
= $24\times 2.875=69L$
So, the quantity of the diesel consumed by the generator to run for 24 hours is 69 L.
The correct option is D.

Additional information:
Even after it is a very basic question, where we just need to get the quantity of diesel required to run a generator for a day that can be obtained by multiplying diesel consumed per hour with the no. of hours in a day. But we also should know about the basic operation applied here. i.e., multiplication.
Multiplication is one of the four basic operations in mathematics which is used in solving problems & in our daily life too.

Note:In this type of problem, for time at any hour if required diesel is to be calculated, the solution can be obtained by simply multiplying the quantity of diesel consumed per hour. Do the calculation carefully so that you ensure that you don’t make a mistake even after knowing the way to do it. Basic operation applied here i.e., Multiplication. Don’t forget to write units of volume with the answer because a no. is meaningless without a unit.
