Observation
Few candidates who attempted the question did not follow the arithmetical sequence the question demands.
The responses expected from candidates are:
(a) Total Cost is the  overall expenditure incurred in producing a specific quantity of 
    goods. It is the sum of variable and  fixed costs.                          
    (b)  (i) Quantity of Trousers = 50 pairs
    Unit  cost of production = N800
    Total  cost of production = quantity x unit price
    =  50 x N800                            
    =  N40,000                               
    (ii)  Quantity of shirts              =           70 pieces
    Unit  cost of production          =          N450
    Total  cost of production         =          Quantity x unit price
    =          70 x N450                                                                                                                               =          N31,500                      
    (iii)  Profit made on producing trouser at 10%
    =          10 x N40,000                                                  
    100      1
    =          N4000                                                             
    (iv)  Profit made on shirts at 10%
    =          10 x N31,500                                                  
    100      1
    =          N31,500                                                          
    (v)  Total profit made on the venture
    Profit  from trouser =               4000    
    Profit  from shirts =                 3150    
    Total profit =                            7150
