Statement is lengthy, so I have attached the picture of it?

Assuming
Cost of manufacturing
#C_m = kn#
where#k# is the constant of proportionality for production of#n# items
From the given information
#20000 = kxx200#
#=>k = 20000/200#
#=>k = 100#
As cost of manufacturing is
Storage cost
#C_S = k_sn^2#
where#k_s# is the constant of proportionality for storing#n# items
From the given information
#360 = k_sxx(200)^2#
#=>k_s = 360/(200)^2#
#=>k_s = 0.009#
#:.C_S = 0.009n^2#
Overall daily cost
#Q = 100n + 0.009n^2 + 9000#
Rearranging in order of descending value of exponent
#Q = 0.009n^2 + 100n + 9000#
For values of#n" between "0 and 200#
