E 56,000

Total Revenue for the Year 2012 is $$2,40,000$$
Total revenue for the first 10 years ( Jan 2012 - Oct 2012 ) is $$1,80,000$$

So, The Revenue for November 2012 & December 2012 is $$60,000$$

Let revenue for Nov be $$x$$ , so revenue in Dec is $$\frac{3x}{2}$$

Thus, $$\frac{3x}{2} + x = \frac{5x}{2} = 60,000$$

So, $$x = 24,000$$ , Answer must be (A) 24,000
