let cp=100
then labour(65%)=65
material(35%)=35
sold at profit of 50% then sp=150;
now labour cost increase by 20% then 65+.2*65=78;
now sp is increased by 30% then new sp=150+.3*150=195
still profit of 50% then cp=195/1.5=130;
material cost =new cp-laour=130-78=52
increased in material cost =((52-35)/35)*100=48.5%
