Step-by-step explanation:
In the first case
x+0.2x=24000
1.2x=2400
x= 20000
And
y-0.2y=24000
0.8y=24000
y=30000
He lost 6000 in case 2 andgained 4000 in the 1st.
Collectively he list 2000
Total selling price = 24000*2=48000
Cost price of first computer is:
24000*100/120=20000
Cost price of second computer is:
24000*100/80= 30000
Total cost is 20000+30000= 50000
So total gain is 50000–48000= 2000
So, gain percentage is: 2000*100/50000=4%
Sale price of first computer = Rs 24000
gain = 20%
So cost of first computer = 100/120 x 24000 = Rs 20,000
Sale price of second computer = Rs 24000
Loss 20%
So cost of second computer = 100/80 x 24000 = Rs 30,000
Total cost = Rs 50,000
Total sale value = Rs 48000
Loss = Rs 2000
Loss % = 2000/50000 x100= 4 % LOSS ANSWER
