Cost slope (Rs./day) A project has four activities P, Q, R and S as shown below. Activity P Q R S Normal duration (days) 3 7 4 5 Predecessor P P R 500 100 400 200 The normal cost of the project is Rs. 10,000/- and the overhead cost is Rs. 200/- per day. If the project duration has to be crashed down to 9 days, the total cost (in Rupees) of the project is Consider the following data with reference to elementary deterministic economic order quantity model Annual demand of an item Unit price of the item (in Rs.) Inventory carrying cost per unit per year (in Rs.) 100000 10 1.5 30 Unit order cost (in Rs.) The total number of economic orders per year to meet the annual demand is A mild steel plate has to be rolled in one pass such that the final plate thickness is 2/3rd of the initial thickness, with the entrance speed of 10 m/min and roll diameter of 500 mm. If the plate widens by 2 % during rolling, the exit velocity (in m/min) is A rectangular hole of size 100 mm x 50 mm is to be made on a 5 mm thick sheet of steel having ultimate tensile strength and shear strength of 500 MPa and 300 MPa, respectively. The hole is made by punching process. Neglecting the effect of clearance, the punching force (in kN) is (A) 300 (C) 600 (B) 450 (D) 750
