Questions & Step-by-Step Solutions

A man earns $1200 after a 20% increase in his salary. What was his original salary?
Correct Answer: 1000
  • Step 1: Let the original salary be represented by 'x'.
  • Step 2: A 20% increase in salary means the new salary is 'x + 0.2x'.
  • Step 3: Combine 'x' and '0.2x' to get '1.2x'.
  • Step 4: Set the equation '1.2x = 1200' because the new salary is $1200.
  • Step 5: To find 'x', divide both sides of the equation by 1.2: 'x = 1200 / 1.2'.
  • Step 6: Calculate '1200 / 1.2' to find the original salary.
  • Percentage Increase – Understanding how to calculate the original value before a percentage increase is applied.
  • Algebraic Manipulation – Using algebra to solve for an unknown variable in an equation.
