1. What is the use of the Scenario Manager in LibreOffice Calc? (LibreOffice Calc-āϤ Scenario Manager ā§° āĻŦ্āĻ¯ā§ąāĻšাā§° āĻ•ি?)
Answer: The Scenario Manager is used to create and manage different sets of values (scenarios) in a spreadsheet, allowing users to compare possible outcomes.

2.What is Goal Seek in LibreOffice Calc? (LibreOffice Calc-āϤ Goal Seek āĻ•ি?)
Answer: Goal Seek is a tool used to find the required input value needed to achieve a desired result by adjusting a specific cell's value.
(Goal Seek-āĻ āύিā§°্āĻĻিāώ্āϟ āĻĢāϞাāĻĢāϞ āϞাāĻ­ āϕ⧰িāĻŦāϞৈ āĻāϟা āύিāϰ্āĻĻিāώ্āϟ āĻ•োāώ⧰ āĻŽাāύ āϏাāĻŽāĻž্āϜāϏ্āϝ āϕ⧰ি āĻĒ্⧰⧟োāϜāύী⧟ āχāύāĻĒুāϟ āĻŽাāύ āĻĒোā§ąা āϏāĻšা⧟ āϕ⧰ে।)

Answer: Scenario: It allows comparing multiple possible outcomes by creating different sets of values.
Goal Seek: It finds the required input value to achieve a specific output.
(Scenario: āĻāϟি spreadsheet-āϤ āĻŦিāĻ­িāύ্āύ āĻŽাāύ⧰ āϏāĻŽāώ্āϟি āϏৃāώ্āϟি āϕ⧰ি āϏāĻŽ্āĻ­াā§ą্āϝ āĻĢāϞাāĻĢāϞ āϤুāϞāύা āϕ⧰িāĻŦ āĻĒাā§°ে।
