If C's revenue is Difference of total and $225000, then A + B must be 225000.

Given B as 150,000, A's revenue will be $75000.

If 25% of revenue is $75000 then. $150,000 i.e. t% is 50%

Answer is A

OA:

Let the total revenue be X.

So X= A + B+ C

which is X= 1/4 X+ 150 + (X-225)

4X= X+ 600 + 4X -900

Solving for X you get X= 300

And 150 is 50% of 300 so the answer is 50 % (A)
