Question

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?

A. 30%
B. 70%
C. 100%
D. 250%​

Answer 1

Answer:

Answer:

Option B

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 = 295/400 x 100 % = 1475/21 % = 70%

Answer 2

Solution

let the cost is =X rs

therefore the profit=(320x/100)rs

now..

the selling prize is

=(X+320x/100)rs=(420x/100)rs

now..cost prize is=(125x/100)rs

but the selling prize is=(420x/100)rs

therefore..now the profit is

=[(420x/100)-(125x/100)]rs

=(295x/100)rs

now..

percentage of the profit price to the selling prize

$\frac{ \frac{295x}{100} }{ \frac{420x}{100} } \times 100 \\ = \frac{29500}{420}$

=70.24%(approx)
