Answer 2

Given data :

• Werner's salary is 20% of his boss.

To find :

• By what percentage should Werner's salary increase to become equal to his boss's salary?

STEP-BY-STEP SOLUTION :

Let, boss's salary be x.

Then Werner's salary is (x * 20/100) = 20x/100

Let Werner's salary should be increased by r% to become equal to his boss's salary. Then

• 20x/100 (1 + r/100) = x
• or, x/5 (1 + r/100) = x
• or, 1 + r/100 = x * 5/x
• or, 1 + r/100 = 5
• or, r/100 = 4
• or, r = 400

Answer:

Therefore Werner's salary should be increased by 400% to become equal to his boss's salary.
