Question

By selling an article for 400, a gain will be of 25 rupee. At what price he sell the article to gain 20 percent

Answer 1

Selling price of an article ${=\:Rs.\:400}$

Gain ${=\:Rs.\:25}$

So,

Cost price of an article

$= Rs.400 - Rs.25$

$= Rs.375$

To have a gain of $20\%,$

Selling price

$= 375 + 375 \times \frac{20}{100}$

$= 375 + 75$

$= 450$

Therefore selling price of an article should be $Rs.450$ to have a gain of $20\%.$

Answer 2

S.P = 400,
Gain = 25,
C.P = S.P - gain
= 400 - 25 = 375.

Amount with gain 20%
= 20/100 × 375
= 75.

S.P with gain20%
= 75 + 375
= 450.

Hence, the total amount
= rs.450.
