Question

on selling a computer for Rs 24480, a dealer loss 4%.for how much should he sell it to gain 4%?

Answer 1

Solution:-

Let the C.P. of the computer be Rs. 'x' 
So, according to the question.
x - 4 % of x = 24480
x - x/25 = 24480
(25x - x)/25 = 24480
24x/25 = 24480
24x = 612000
x = 612000/24
x = 25500
So, the cost price of the computer is Rs. 25500
Now, we require selling price of the computer at 4 % gain.
Gain = (25500*4)/100
Gain = Rs. 1020
Selling price = Cost price + gain
S.P. = 25500 + 1020
Selling Price = Rs. 26520
Thus, to get a gain of 4 %, he should sell the computer at Rs. 26520.
