x/6=c,
x/2=d

x = 360
x = 1/5*x + 1/8*x + 1/6*x + 1/2*x + 3
x = 24/120*x + 15/120*x + 20/120*x + 60/120*x + 3
x = 119/120*x + 3
1/120*x = 3
x = 360

Ans is: X=360 .............so simple

x = (12x+7.5x+10x+30x+180)/60
60x = 59.5x+180
0.5x=180
x=360

480X = 96X+60X+80X+240X+(3x480)
480X - 476X = 1440
X = 1440/4 = 360

x=360
i.e
x = a+b+c+d
= x/5 + x/8 + x/6 + x/2 +3..............(1)

multiplying eqn 1 above by 120 (LCM of 5,8,6,2) throught,

120x = 24x + 15x + 20x + 60x+ 360
= 119x +360
120x - 119x =360

x = 360

x/5+x/8+x/6+x/2+3=x
(96x+60x+80x+240x+1440)/480=x
(476x+1440)/480=x
476x/480+3=x
x-476x/480=3
4x/480=3
4x=1440
x=360

x = 360
x = 1/5*x + 1/8*x + 1/6*x + 1/2*x + 3
x = 24/120*x + 15/120*x + 20/120*x + 60/120*x + 3
x = 119/120*x + 3
1/120*x = 3
so the right answer is x=360...
