Q1. What is Difference between LSM and WSM?
Ans. 
LSM (Least Squares Method) minimizes error in data fitting, while WSM (Weighted Sum Method) uses weights for decision-making.
• LSM focuses on minimizing the sum of the squares of the errors between observed and predicted values.

• WSM aggregates multiple criteria by assigning weights to each criterion based on importance.

• Example of LSM: Fitting a line to data points in regression analysis.

• Example of WSM: Evaluating project ...read more

Q2. What is slump cone test ??
Ans. 
The slump cone test measures the workability and consistency of fresh concrete.
• The test involves filling a conical mold with concrete and lifting it to observe the slump.

• A higher slump indicates more workability, while a lower slump suggests a stiffer mix.

• Typical slump values range from 0 to 10 inches, depending on the application.

• For example, a slump of 3-4 inches is suitable for structural concrete, while 5-7 inches
