During the period from 2014 to 2015, the revenue increased by 25% for three of the companies and by 50% for the remaining company. The total increase in revenue, for all four companies put together, was Rs. 125 lakhs.
Which of the following CANNOT be true?

Let us first compute the individual changes in value in both years before zeroing in on the companies that fall into the 25% increase and 50% increase groups. 

For 25% increase:

For 50% increase: 

We can move forth with the assumption that P saw a 50% increase while the rest of the companies saw a 25% increase. In this case, the total increase in revenue, for all four companies put together, will be Rs. 125 lakhs. Same is the case when we consider company R to have seen a 50% increase, while the rest had a 25% increase. {Hence, Option D is true} We observe that Options B, C and E hold true as well. The increase observed for each of the companies is distinct, based on the given condition. Thus, Option A cannot be true.
