This research became applied quantitative research design to measured data due to Numerical and to get appropriate and specific statistics the frame of the researchers. This model examines how Inventory model can assist in minimising the total cost of Inventory model. The Trapezoidal guideline works by approximating the region under the graph of the capacity f(x) as Trapezoid and computing its area. It is ruled to locate the estimation of a positive fundamental utilizing numerical technique.

Let f(x) be continuous in the line [p,q] and DC be the curve Y = f(X) and DC, CB is terminal Ordinates.

Let OA = p and OB = q, then, AB = OB−OA = q−p

Divide AB into n same segment A, A₁, A₁A2……..An−1B

So that each segment

Portray the ordinate among

and put then be referred as Y₁,Y_2………YN,Y_N+1 respectively,

Then

(1.21)

where, A = Sum of the first and last ordinates

(1.22)

B = Sum of the remaining Ordinates as Trapezoidal rule
