There are 1800 kg apples and pears in a fruit shop. One eighth of the apples are sold and 600 kg pears are imported. At this time, the apples are the same as pears. How many kg are the original apples

Suppose the original apple x kg, the pear is 1800-x kg, (1-1 / 8) x = 1800-x + 600
15x=2400*8
The solution is x = 1280
Original apple 1280 kg
