please, try to explain how can get the answer without used excel
Total Annual $ Value = 57956
Total units/year = 4937
Let us now calculate the % contribution of each item to Annual Vaule (Annual Value of item/Total Annual Value)
A = 700/57956 = 1.21%
B = 1.81%
C = 6.66%
D = 4.43%
E = 0.52%
F = 42.52%
G = 30.42%
H = 1,77%
I = 9.97%
J = 0.69%
Similarty let us calculate unit contribution to total unites for each item
A = 14.18%
B = 1.42%
C = 19.55%
D = 10.41%
E = 0.41%
F = 15.60%
G = 12.32%
H = 10.39%
I = 11.71%
J = 4.03%
Item F and G contribute maximum towards total Annual $ Value
Total Units for F & G = 15.60% + 12.32% = 27.91%
Total Annual $ Revenue for F&G = 42.52% + 30.42% = 72.94%
Hence F & G can be classified under A category (so nearly 30% of units contribute to nearly 70% of revenue)
Let us now look at the next biggest items from Annual $ Revenue - C, D & I
C, D & I form 19.55% + 10.41% + 11.71% = 41.66% of total units
C, D & I contribute to 6.66% + 4.43% + 9.97% = 21.07% of total Annual $ Revenue
Hence, C, D & I can be classified in Category B (nearly 40% of the units contribute to 20% of the revenue)
Remaining - A, B, E, H, J contribute 30.42% towards the total number of units and 5.99% of the total Annual $ Revenue
Hence A, B, E, H, J can be classified in Category C
