Company P’s profit this year was what percent of its profit last year?

(1) Company P’s total profit for this year and last year combined was $15,000.
(2) This year, Company P’s profit was $5,000.


From the Question,It is clear that we must have to know the direct proportion/amount of each year's profit of the company.

Statement(1) Just told the total profit without any particular amount of each year. Insufficient

Statement(2) Didn't told any thing about previous year's amount/proportion,Insufficient

(1)+(2) together gave previous years amount( $15000-$5000=10000),which was double than this year,Sufficient

Correct Answer C

Nice Question.
Let this years profit => $y
Last year profit => $x

Let p be the required percentage
(p/100)*x=y
=> p=y/x*100
so we need both the last years as well as this years profit.
Statement 1 => x+y= 15000
NOTE=> If we are given x+y we can never get x/y unless some other constraint is provided.
Not sufficient.
Statement 2 =>
Clearly not sufficient as we don't know x
Combining them we can say that p => 5000/10000 *100 => 50 percent
Hence C
