The cost price of 20 articles is the same as the selling price of x articles. If the profit is 25%, then the value of x is:
Answer: Option
Explanation:
Let C.P. of each article be Re. 1 C.P. of x articles = Rs. x.
S.P. of x articles = Rs. 20.
Profit = Rs. (20 - x).
 |
 |
20 - x | x 100 = 25 |  |
| x |
2000 - 100x = 25x
125x = 2000
x = 16.

If 20 article=100rs then each article=100/20=5.
X article= 100rs then each article=100/X,
Formula- %profit={(SP-CP)/CP}*100.
25={(100/X-5)/5}*100,
25={(100-5X/X)/5}*100,
25={(100-5X)/5X}*100,
25/100={(100-5X)/5X},
(1/4) 5X=(100-5X),
5X = 400-20X,
5X+20X = 400,
25X = 400,
X = 400/25=16.
X article= 100rs then each article=100/X,
Formula- %profit={(SP-CP)/CP}*100.
25={(100/X-5)/5}*100,
25={(100-5X/X)/5}*100,
25={(100-5X)/5X}*100,
25/100={(100-5X)/5X},
(1/4) 5X=(100-5X),
5X = 400-20X,
5X+20X = 400,
25X = 400,
X = 400/25=16.

Profit 25% = 125#
125 - 20
100 - ?.
100 * 20/125 = 16.
125 - 20
100 - ?.
100 * 20/125 = 16.

(20) cp=(x) sp ------> 1.
Profit=25%.
Means
sp = 125% of cp.
sp = 125/100*((x*sp)/20) {because 1}.
1= 125*x/100*20.
2000/125 = x.
X = 16.
Profit=25%.
Means
sp = 125% of cp.
sp = 125/100*((x*sp)/20) {because 1}.
1= 125*x/100*20.
2000/125 = x.
X = 16.

It is given that;
20(C.P)=x(S.P).
And we know that,
Profit=(SP-CP) /CP.
Therefore,0.25=(SP-(SP*x/20))/(SP*x/20)).
Solving the equation we have,
x=16.
20(C.P)=x(S.P).
And we know that,
Profit=(SP-CP) /CP.
Therefore,0.25=(SP-(SP*x/20))/(SP*x/20)).
Solving the equation we have,
x=16.

Cost = Rs 100 For 20=Rs2000,
Sale price of x articles= Rs 2000,
Profit 25% sale price Rs125,
125x = Rs 2000,
X= 2000/125= 16.
Sale price of x articles= Rs 2000,
Profit 25% sale price Rs125,
125x = Rs 2000,
X= 2000/125= 16.

Profit=(20-x).
How it is Possible ?
Profit Means;
For Example One Item Bay 2 Rupees, This Item sell 4 Rupees.
Then Profit 2 Rupees.
Profit How To Calculated.
= Sp-Cp.

We can solve these problem by using another method.
Given 20 C.P.=x S.P --> eq1.
but the profit is 25%.
Therefore, SP=(125/100)*CP.
put above value of SP in eqn 1.
20*CP=x*(125/100)CP.
By solving x=16.
