given:Â
total order placed for a : 110 units.Â
currently available units of a : 60 units.Â
4 units of b required for each aÂ
current available units of b =20Â Â
solution:Â
remaining a to be produced= 110-60= 50 unitsÂ
so, units of b required =50*4=200 units.Â
remaining units of b required=200-20=180 units.Â
net requirements for b= 180 units.
