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 |

Given:
profit=320%.
C.P = increases 25%.
S.P = remains constant.
Asking, S.P % if C.P is increased 25% for the profit 320%?
Generally, when C.P. increases 25% obviously S.P decrease 25% for the same 320%profit.
i.e, S.P - C.P = Profit.
If, S.P(100) - C.P(100) = 320.
Then, C.P(125) - S.P(75) = 320 [when C.P increases 25%],
Therefore, S.P = 75%,
Approximately, S.P = 70%.
profit=320%.
C.P = increases 25%.
S.P = remains constant.
Asking, S.P % if C.P is increased 25% for the profit 320%?
Generally, when C.P. increases 25% obviously S.P decrease 25% for the same 320%profit.
i.e, S.P - C.P = Profit.
If, S.P(100) - C.P(100) = 320.
Then, C.P(125) - S.P(75) = 320 [when C.P increases 25%],
Therefore, S.P = 75%,
Approximately, S.P = 70%.

@All.
Here they took SP in the denominator because in the question they asked "what percentage of SP is the profit".
Correct me, if I'm wrong.

Profit % = (s.p - c.p )*100/c.p.
say c.p = 100 Re.
Therefore s.p=420 Re
The cost inc by 25% = 125 Re,
s.p = 420 Re.
The profit it requires percent of the selling price = (420-125/420)*100 = 70%.
say c.p = 100 Re.
Therefore s.p=420 Re
The cost inc by 25% = 125 Re,
s.p = 420 Re.
The profit it requires percent of the selling price = (420-125/420)*100 = 70%.

While calculating profit%, we should have to take CP in the denominator right? why they took SP?
Anyone, please explain it.

We always calculate with cost price, we can't take profit percentage on selling price,then how could you take s.p over c.p?
Please explain me.
Please explain me.

Profit = Rs. (420 - 125) = Rs. 295.
Required percentage = (Profit/Cost Price) * 100 = Rs. (295/125)*100 = 236%
Ans = 250% (approximately).
New C.P. = 125% of Rs. 100 = Rs. 125.

Let Cp = 100.
Gain = 320
SP = 420
Now;
Gain% = Gain ÷ sp * 100.
= 420-125/420 * 100.
= 295/420 * 100
= 29500 ÷ 420
= 70%.
Gain = 320
SP = 420
Now;
Gain% = Gain ÷ sp * 100.
= 420-125/420 * 100.
= 295/420 * 100
= 29500 ÷ 420
= 70%.

(Gain/C.P)*100 = 320.
Taking C.P as 'x' & S.P as 'y',
We can get S.P as a function of C.P:
(y-x)/x = 320/100.
y=4.2x.
Gain as a percentage of S.P when only C.P increases by 25%:
New C.P = x + 25x/100.
= 1.25x.
S.P = y = 4.2x i.e unchanged.
(S.P - C.P)*100/S.P = (4.2x - 1.25x)*100/4.2x.
= 70%.
