assume normally N items are produced at cost C
if additiona n items are produced then actual cost = (N+n) * C

But over production causes savings by x dollars per unit
So savings = (N+n) * x these savings should will be depleted if n itemas are stored for d number of days at y per day

so n*y*d = (N+n)*x
d = x(N+n)/yn = x/y[ 1+N/n ]

none of the answers match this

I guess we have to assume N=0 for this problem in which case the ans is x/y

What's the OA?

total amount saved for n units XN
total amount spent on storing N units = YND where D is # of days

there fore when YND = XN

D = X/N :)
