How to find out profit on sales when tc is given?

profit is 36000/-(144000*1/4 or 144000*100/80)) sales is 180000/- sale price per unit is 120/-

TOTAL COST         Rs. 144000

+ PROFIT                20% on sales

= SALES                          ?? 
 

  then, assuming sales to be 100.. if the sales are 100 then profit wud be 20(100*20%on sales) . .

 likes wise by this method u can simply calculate profit and sales .. .

profit = 144000*20/80 . that gives Rs.36000[profit]

sales= 144000+36000[total cost+profit]= 180000 [sales] .

Follow three simple steps :

Step 1 - Convert percentage of profit to fraction. Here say 20% i.e 20/100(as 100 is the base for percentage)

Step 2 -  Check the percentage of profit given if on sales or cost

Step 3 - To arrive at profit percentage from Cost to sales or vice versa follow the below formulae :

a) Sales to cost : above example : fraction 1/5(sales), to cost  1/5-numerator = 1/5-1=1/4

Profit = 144000*1/4=36000

b) Cost to Sales : Take above example : Sales = Cost + profit = 144000+36000=180000

Profit percentage on cost in fractions we have 1/4

on sales = 1/4+1=1/5

Profit = 180000*1/5=36000.
