A dealer bought 18 toy chairs at Rs. 65 per chair he sold 12 of them at Rs. 75 each and the remaining chairs at rs

60 each find his profit or loss percentage

7.7%

Step-by-step explanation:

spent = Rs. 65*18 = Rs. 1170

earned = 12*Rs. 75+6*Rs. 60 = Rs. 1260

profit = Rs. 1260 - Rs. 1170 = Rs. 90

profit % = 90/1170*100% = 7.7%

The dealer's profit percentage is 7.692%

Step-by-step explanation:

18 * 65 = 1170

He spent Rs. 1170

12 * 75 = 900

60 * (18-12) = 360

900 + 360 = 1260

He got a profit of Rs. 90.

1170 * (1 + x/100) = 1260

1 + x/100 = 14/13

x/100 = 1/13

x = 7.692307692
