Produced 4x


March April May June July A S O

3.5 3 2.5 2 1.5 1 0.5


In march, out of 4x, x is sold hence 3x. this happens till October where all is sold.

In April, out of 3.5 x, 0.5x is sold, hence 3 x is pending in April

and so on....


hence charges for

3.5+3+2.5+2+1.5+1+0.5=14x rakes

0.1 $ per rake each month

Total storage cost=14 x*0.1 =1.4 X ( in $)

IMO C
