A dealer sells two machines at the rate of Rs. 15000 per machine. On one he earns a profit of 20 percent and on the other he loses 40 percent. What is his profit/loss percentage in the whole transaction ?
Answer & explanation

Loss % = 40% = \(\frac{2}{5}\)
Profit % = 20% = \(\frac{1}{5}\)
CP SP
1st 5 6
2nd 5 3
Given SP is equal so make SP equal
CP SP
1st 5 6
2nd ( 5 3)× 2
CP SP
1st 5 6
2nd 10 6

15 12
Loss = 15 - 12 = 3
Loss% = \(\frac{3 × 100}{15}\)= 20%
