# What can be cost of the two article?

A discount of 15% on one article is the same as a discount of 20% on another article. The cost of the two article can be:

- Rs. 40, Rs. 20
- Rs. 60, Rs. 40
- Rs. 80, Rs. 60
- Rs. 100, Rs. 80

**Answer: (3) Rs. 80, Rs. 60 **

**Solution:-**

Let the cost of one article be X and cost of another article be Y.

A discount of 15% on one article is the same as a discount of 20% on another article.

Then, X x 15/100 = Y x 20/100

3 X = 4 Y

X/Y = 4/3

X/Y = 4 x 20/3 x 20

X: Y = 80 : 60

Then, the cost of the two article can be Rs. 80 and Rs. 60.

Hence, the correct answer is option (3) Rs. 80, Rs. 60.
