Hi himu,

Can you post the entire original prompt?

Some of what you've typed is unclear. When the question states that "the profit is 25%", does that refer to 25% of the sell price or 25% of the cost?

GMAT assassins aren't born, they're made,

profit % is 25%

% P = (SP-CP)/CP X 100

What I infer is 25% is the profit when x articles are sold at cost price of 25 articles.

Your thoughts pls? Correct me if I am wrong.

The intent of the problem seems to be as follows:
At a certain store, the selling price of each shirt is equal to the cost price of each shirt plus a 25% markup. The total selling price of x shirts is equal to the total cost price of 25 shirts. What is the value of x?
Let the cost price of each shirt = $4.
Total selling price of x shirts = total cost price of 25 shirts = 25*4 = $100.
Selling price per shirt = cost price per shirt + 25% markup = $4 + 25% of $4 = $5.
Thus:
x = (total selling price)/(selling price per shirt) = 100/5 = 20.

This is how I understood it.

Profit% = (profit/C.P) *100

S.P = C.P * 25 --- given
C.P = C.P * x

Substitute in the above formula..

(c*25 - c*x)/c*x= 1/5

on solving we get x=30

Let S.P = S
Let C.P = C

Therefore, according to the ques, Sx = 25C

Now, Profit = S-C/C = 1/4
Solving this, 4S=5C
Multiply by 5, 20S=25C

Therefore, x=20
