#color(green)("Increase % " = 16%, " rounded to whole number"#

Explanation:

#"Initial Salary " S_i = $ 120.00#

#"Revised Salary " S_r = $ 140.00#

#"Increase in Salary " I = S_r - S_i = 140 - 120 = $20#

#"Percentage Increase " I_p = (I / S_i) * 100 = (cancel20/cancel(120)^color(red)(6)) * 100#

# => 100/6 % = 16.25% = 16%, " rounded to whole number"#
