Statement 1: Let the revenue from consumer products be 10000 and machine products be 9000 in 2014. And K = 10%
Consumer products 10% increase= 10000+1000=11000 and machine product 10% decrease= 9000-900=8100
So total revenue for 2015 is 19100 which is overall increase in revenue from 2014. So statement 1 is alone sufficient.
Statement 2: we don't know whether there is an increase and decrease in overall revenue or any of that so K=8 is not sufficient. So OA is A.

The successive percentage formula works when a single quantity is first increased and then decreased, or vice versa.

But in this question, the increase and decrease apply to two separate revenue streams - not the same quantity - so the formula doesn’t apply.
