Method 1:- By Alligation, Supervisor labours 7200 4800 5600 800 : 1600 1 : 2 So number of labour = twice of number of supervisors = 2`xx` 24 = 48 So total number of employees = 24+48= 72 Method 2: Let the number of Labour = x So 24*7200 + x*4800 = (24+x)*5600 24*72 + 48x = (24+x)*56 24*72+48x = 24*56 + 56x 56x - 48x = 24*72 - 24*56 = 24(72-56) = 24*16 8x = 24*16 x = 24*2 = 48 So total number of employees = 24+48= 72
