A shopkeeper sold an article at a loss of 20%. But if he could sell it at Rs.200 more, he could earn a profit of 5%. The cost price of the article is

- Rs.1,000
- Rs.1,200
- Rs.600
- Rs.800

**Answer is Rs.800.**

**Explanation:-**

Let the cost price of an article be Rs. X

According to the question,

X x 105/100 – X x 80/100 = 200

21 X/20 – 16 X/20 = 200

21 X – 16 X = 200 x 20

5 X = 4, 000

X = 4, 000/5

X = 800

Then, the cost price of the article is Rs. 800.

Hence, the correct answer is option (4) Rs. 800.
