Q1. Convert hexadecimal to decimal ?
Ans. 
Hexadecimal to decimal conversion involves multiplying each digit by 16 raised to the power of its position.
• Start from the rightmost digit and multiply each digit by 16 raised to the power of its position (0-indexed).

• Add the results of each multiplication to get the decimal equivalent.

• For example, converting 0x1A to decimal: (1 * 16^1) + (10 * 16^0) = 26.

Q1. When 2 trains move in opposite directions , what point will they meet at different speeds? And related questions
Ans. 
The trains will meet at a point that is determined by the relative speeds of the trains.
• The point where the trains meet is determined by the sum of the distances traveled by each train.

• The time taken for the trains to meet is determined by the relative speeds of the trains.

• If Train A is traveling at 50 mph and Train B is traveling at 70 mph, they will meet at a point that is closer to Train B's starting point.
