4.
In a certain store, the profit is 320% of the cost. If the cost increases by 25% but the selling price remains constant, approximately what percentage of the selling price is the profit?
Answer: Option
Explanation:
Let C.P.= Rs. 100. Then, Profit = Rs. 320, S.P. = Rs. 420.
New C.P. = 125% of Rs. 100 = Rs. 125
New S.P. = Rs. 420.
Profit = Rs. (420 - 125) = Rs. 295.
 Required percentage = |
 |
295 | x 100 |  % |
= | 1475 | % = 70% (approximately). |
| 420 | 21 |

Let me explain you clearly:
In most of the problems assume cp as 100 then only it will be easy.
now let us assume cp=100
profit is given 320%
we know p=sp-cp
then sp=p+cp
so sp=420
Then it is given cp is incresed by 25%
so cp=alredy assumed as 100+now increased by 25%
cp=125
sp is always constant(given in question)
so now sp=420
cp=125
p=sp-cp
=420-125
=295
p%=p/cp*100
But here it is specifically asked for sp(read the question)
so p%=p/sp*100
=295/420*100
=70%

I had not understood the explanination. Can you please explain me it again. How can we assume cp to be 100?

Maths & Physics are completely based on assumption based foundations....even in this example no data about CP is given...so we have no choice just assume a simplified value (eg 100 or 1) and base your calculations upon that !!!!

Good explanation malini.

Hi nitesh if we take cp=100 your principle not works.

Why sp 420 is calculated when it is given that sp will remain constant?

Nitesh your Answer is verry nice and Simple.
But 1000 is Working 1000 increased by 25% it became 1250 , but if u take 100 incresed by 25% it became as 125 then the Problem is Wrong .. If we assume anything it will be satisfied to all the Methods.

What percentage of the selling price is the profit?
In maths formula is a basic, but we have to understand it in different views. Then we make it up easy. Sundar is correct.

Profit=selling price-cost price
But profit is given in percentage and i thought that as profit percentage.
But we use it like profit i.e. Rs.320. How is this possible?
