Tip 1 : Let the age of son = X years
Tip 2 : ∴Age of mother would be =2X
Tip 3 : As per question 20 years ago;

10 (X -20) = 2X - 20

10X - 200 = 2X - 20

10X - 2X= - 20 + 200

8X = 180

X=Apti Problem on ages 13= 22.5 years

∴Age of mother = 22.5 * 2 = 45 years

Tip 1 : The year 1996 is divisible by 4, so it is a leap year with 2 odd days.
Tip 2 : As per the question, the first day of the year 1996 was Monday, so the first day of the year 1997 must be two days after Monday. 
Tip 3 : So, it was Wednesday.

Tip 1 : A runs 1km = 1000 m, it means B runs 1000 - 40 = 960 meters
Tip 2 : Time is taken by B for 40 meters = 5 seconds
Tip 3 : Time is taken by B for 960 meters = Races and Games× 960=120 seconds

The time in which B covered 960 meters, A has covered 1000 meters.
∴ A's time over the course = 120 seconds
= 2 minutes

Following are some of the critical characteristics of OOPs: 

1. OOPS allows you to specify the variables of each data item by combining the code into a single unit. 2. Encapsulation is the process of grouping information into a single unit. 
3. One can standardize your objects and make your program easier to use by utilizing classes. We refer to this as an abstraction. 
4. More code can be reused when a class can inherit traits and behaviors from other courses. 
With the aid of polymorphism, numerous objects can be produced from a single, flexible class of code.

The following are some typical OOPs limitations: 

More prominent than other programmes in terms of size. 
It was labor-intensive to create, and it ran slower than other programmes. 
For some problems, it is improper. 
It needs some adjustment.

Tip 1 : Focus on describing a problem that was related to your work using the STAR approach.
Tip 2 : Do not answer negatively or bad-mouth any supervisor or any company.
Tip 3 : Focus on the learnings of the problem rather than dwelling too much on the damage.
