Answer 2

Answer:

The cost price of the article is ₹60.

Step-by-step explanation:

Given : By selling an article for ₹ 78, the profit percent is twice as when it is sold for ₹ 69.

To find : The CP of the article.

Solution :

We know,

Profit = Revenue - Cost  

Let the Cost price = x

By selling an article for ₹ 78

Profit is $P_1=78-x$

By selling an article for ₹69

Profit is $P_2=69-x$

The profit percent is twice as when it is sold for ₹69.

$P_1=2P_2$

$78-x=2(69-x)$

$78-x=138-2x$

$x=60$

Therefore, The cost price of the article is ₹60.
