Question

By selling an article for rs. 69, there is a loss of 8% when the article is sold for rs 78 the gain or loss percent is

Answer 1

CP of article = sp×100/100-L%
= 69×100/92
= RS.75
SP of article = RS.78
As the SP is greater than CP we get loss
Profit percent = (SP - CP)/CP × 100
= (78-75)/75 × 100
= 3/75 × 100
= 4%

Answer 2

Answer:

The gain percent is 4%.

Step-by-step explanation:

Given : By selling an article for Rs.69, there is a loss of 8%.

To find : When the article is sold for Rs.78 the gain or loss percent is ?

Solution :

The selling price of an article is Rs.69.

The loss percent is 8%.

The cost price of the article is given by,

$CP=\frac{100}{100-L\%}\times SP$

$CP=\frac{100}{100-8}\times 69$

$CP=\frac{100}{92}\times 69$

$CP=75$

The cost price = Rs.75

SP of article = RS.78

As the SP is greater than CP we get gain.

Gain = SP-CP

Gain = 78-75

Gain = Rs.3

The profit percentage is given by,

$P\%=\frac{P}{CP}\times 100$

$P\%=\frac{3}{75}\times 100$

$P\%=4\%$

Therefore, The gain percent is 4%.
