Question

A person earns 20% profit by selling a goods at any cost. If he sells it at double cost then, find the profit percent?

Answer 1

let price of good be x. So, at 20% the amount is 20/100*x+x = x/5 + x = 6/5*x. So, double price = 12/5*x. So, profit = (12/5x)-x = 7/5*x. So , % of profit = (7/5*x)/x *100 = 7/5*100 = 7*20 = 140%. please please mark me as brainliest.

Answer 2

Solutions :-

Let the Cost price of goods be Rs 100

Given : Profit = 20%


Find the Selling price of goods :-

S.P = C.P + Profit% of C.P
= 100 + 20% of 100
= 100 + 0.20 × 100
= 100 + 20
= 120



Now, We have

Cost Price = Rs 100
Selling price = Rs 120
New Selling price = Rs (120 × 2) = Rs 240


Profit = S.P - C.P
= Rs (240 - 100)
= Rs 140


Profit % = (profit × 100)/C.P %
= (140 × 100)/100 %
= 14000/100 %
= 140%



Hence,
If he sells it at double price then the profit percent = 140%
