Statement 1
Company R's revenue target for December of next year is 310000

Revenue of March = 310000 - 9X

Not sufficient


Statement 2
Target revenue for September is 30000 more than Revenue in June of next year

Sep - Jun = 3X = 30000
X = 10000

Not sufficient


Combining the two statements
Revenue for march = 310000 - 90000 = 220000


Option C

To find the target in March we need two things. If we know an actual figure for any particular month, we can find the March figure by adding X for each month in between. (Or, if we know a future month figure, subtracting X for each month in between).

1) gives us the first thing i.e. a future month. Without knowing X however, we can't back out March.
2) gives us X, because we know the gap in 3 months is 30000; hence in 1 month it's 10000. But this is insufficient on it's own, as we have nothing to add or subtract X from.

Taking the statements together, we have both things we need. We could subtract 9 months' X (9X) from the December figure to get the March one. Answer: C.

Thanks for your response Are we assuming here that increase in revenue each month is same/constant because otherwise X would Vary right?

After every month, the revenue increases by a particular amount, X, which is a constant.
