Question

On selling a computer for rupees 24480 a dealer loss 4% for how much should he sell it to gain 4%

Answer 1

Answer:

sp of computer= 24480

loss=4%

then, cp = x-x ×4%=24480

x - x × 4/100 =24480

x - x/25 = 24480

25x - x/25 = 24480

24x/25 =24480

x = 24480 × 25/24

x = 25500

For gaining 4% sp = 25500 + 25500 × 4%

25500 + 25500 × 4/100

25500 + 1020

26520

so, he should sell at 26520 to gain 4%
