the price of a maruti car rises by 30% while the sales of the car came down by 20%. what is the percent change in the total revenue?
(a)-4(b)4(c)-2(d)0(e)none of these

• Assume that price is 100 and sales are also 100. Total revenue is 100*100=10000(100%). Now price increased by 30%. So new price is 130. Similarly new sales are 80. Now revenue is 130*80=10400(104%)= So total change is 4%

• since the profit/loss wd be on product
  
  100----->(+30%)------>(-20%) wd give the ans.
  100----->(130)------->130*80/100== 96
  
  (100-96)/100= 4% loss

• b.4 if we cnsider the initial price of car is 100 den increased by 130 and num of car for sales are 10 den reduces to 8 therefore 8*130=1040.

• a> -4 .......100+100*30/100=130..........130-130*20/100=104......total revenue=100-104=-4

• suppose earlier company sales 100 cars.
  now it is 80 cars.
  suppose earlier prize was re 1,now it is 1.3.
  so percent change in revenue = ((1.3*80)-(1*100)*100)/100

• 130*80-100*100=400
  so revenue=4%

• If the profit and loss changes on same thing. We have a formula i.e
  +profit -loss+((profit*loss)/100)
  so, +30-20+(-600/100)
  4%
  so 4% profit

• We can use successive change over here,,,, so 30-20-(30*20)/100
  10-(600)/100
  10-6
  4%
