E. None of these

**Answer: Option C **

__Solution(By Examveda Team)__

Let initial price of Maruti Car be Rs. 100As price increases 30%, price of car will become, (100 + 30% of 100) = Rs. 130

Due to increase in price, sales is down by 20%. It means, it is going make 20% less revenue as expected after increment of price

So, New revenue = (130 - 20% of 130) = Rs. 104

The initial revenue was Rs. 100 which becomes Rs. 104 at the end. It means there is 4% increment in the total revenue

**Mind Calculation Method:**

100 == 30%↑(price effect) ==> 130 == 20%↓(sales effects) ==> 104

Hence, 4% rises
