(1):- The fixed cost its - - with number of products a- Change b- Not change ANSWER - fixed cost is a cost that does not change with an increase or decrease in the amount of goods. So, option "b" is correct (2):- The Machinery costs is ------ a- Variable b- Fixed c- Both ANSWER – machinery cost is to types:- fixed cost - it depends on how long a machine is Owned rather than it is used. it includes interest, tax, insurance etc. Variable cost- this cost varies in proportion to the amount of machine used. it includes repair, maintenance, labour cost etc. so option " c" is correct (3):- The skill of the workers is preferred to be ---------- skill a- Very Poor b- Very Good ANSWER – skilled worker is the one that has knowledge and ability in their work so option "b" is correct (4):- The increasing of the cutting speed that Lead to get--- surfaces a- A very rough b- A very smooth ANSWER – with increase in cutting speed surface finish increase and decrease in cutting speed decreases surface finish so, option " b" is correct (5):- The depth of cut is preferred to be with --- to cutting the hard metal a- Large value b- Small value ANSWER – cut hard material depth of cut should be small so that the tool life do not decrease so, option " b" is correct material science
