A) 18 days B) 12 days
C) 14 days D) 16 days
 
Answer & Explanation Answer: D) 16 days

The analogy here is like this: Veeru has 20 lt of petrol and he uses 1 lt per each day and consumes it in 20 days. If he uses 1.25 lt every day, in how many days it will be consumed?
We considered 1.25 lt here because it’s 25% more than 1 lt.

The answer would be  20/1.25=16 days.

Q:

What is the difference between a constructor and a method?

Answer

A constructor is a member function of a class that is used to create objects of that class. It has the same name as the class itself, has no return type, and is invoked using the new operator. We cannot invoke a constructor directly.


 


A method is an ordinary member function of a class. It has its own name, a return type (which may be void), and is invoked using the dot operator.
