Answer: Option C
Solution(By Examveda Team)
Let initial price of Maruti Car be Rs. 100 As 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% risesJoin The Discussion
