A) Rs.1000 B) Rs. 1020 C) Rs.1210 D) Rs.1140

Answer 1

Answer:

(A)  Rs.1000

Step-by-step explanation:

Given that,

Selling an article at a profit of 20%, Aman gets Rs. 400 more than selling at a loss of 20%

Hence the equation is,

[x + 20/100 * x] + 400 = [x  - 20/100 * x]

where, x is equal to the cost price of the article

[ x + 1/5 * x ] + 400 = [x - 1/5 x]

[6/5 * x] + 400 =  [4/5 * x ]

400 = [4/5 * x] - [ 6/5 * x]

400 = - [ 2/5 * x]

200 = - [ 1/5 * x]

x = 1000
