Question

A man sells two radios for rupees 4000 each . For one he gets a gain of 20% and for the other a loss of 20%. Find his total loss or gain in the whole transaction.​

Answer 1

Answer:

Total loss 8333.33 - 8000 = Rs.333.33

in Percent his loss = 333.33/8333.33  x 100 = 4%

Step-by-step explanation:

SP of first radio = 4000

profit = 20%

CP = x

4000/x   x 100 = 120

x = 3333.33

CP of first Radio = 3333.33

SP of second Radio = 4000

Loss = 20%

CP = y

4000/y  x   100  = 80

y = 5000

CP of second radio = 5000

Total CP = 3333.33 + 5000 = 8333.33

Total SP = 4000 + 4000 = 8000

8000 ∠ 8333.33

SP ∠ CP

So his total loss 8333.33 - 8000 = Rs.333.33

in Percent his loss = 333.33/8333.33  x 100 = 4%
