Answer:
Paul's salary is increased by 6% and John's salary is 2 more than thrice Paul's salary.
Step-by-step explanation:
Paul and John are working in a Company and this month Paul's salary is increased by 6%. John's salary is 2 more than thrice Paul's salary.
If <em>x </em>represents Paul's salary before increment, and <em>y</em> represents John's current salary, find Paul's current salary.
<em>x </em>is Paul's salary before increment.
So, Paul's current salary = <em>x</em> + 6% of <em>x</em>
= <em>x</em> + 0.06<em>x</em>
= 1.06<em>x</em>
John's current salary is 2 more than thrice Paul's salary.
So, John's current salary = 3(1.06<em>x</em>) + 2.
