Let CP of one pen be x. Then, CP of 5 pen = 5x = SP of 4 pen. So, SP of one pen = 5x / 4. Now, Loss = SP - CP = 5x/4 -x = x / 4 Finally, Loss% = Loss / CP X 100% .....
Here, SP = Rs.600 Profit = 1/5 of SP = 1 / 5 x Rs.600 = Rs.120. We know, Profit = SP - CP or, 120 = 600 - CP or, CP = 600 - 120 = RS. 480. Finally, Profit % = Profit / CP x 100% = Rs120 / Rs. 480 x 100% .....
Here, CP of 5 oranges = Rs. 30. SP of one orange = Rs.8. Or, SP of 5 orange = 5 x Rs.8 = Rs. 40. SO, he got gain of Rs.40 - 30 = .....
