after 1/10, 5/6 of the remainder is 5/6 * 9/10 = 45/60 = 3/4
so, x(1 - 1/10 - 3/4) = 1800
3/20 x = 1800
x = 12000
so, x(1 - 1/10 - 3/4) = 1800
3/20 x = 1800
x = 12000

Solution:
x(1-1/10-5/6)=1800
x-x/10-5x/6=1800
L.c.m=30
30x-3x-25x/30=1800
2x/30=1800
2x=54000
x=27000
x(1-1/10-5/6)=1800
x-x/10-5x/6=1800
L.c.m=30
30x-3x-25x/30=1800
2x/30=1800
2x=54000
x=27000
