Solution :
Cost assigned on average cost basis = $ 904.
Cost assigned on FIFO basis = $ 990.
Cost assigned on LIFO basis = $ 680
.
Working :
Average Cost Basis :
Cost on Average Cost Basis = (Total Cost / Total Unit) * Ending Inventory
= ( $ 3,260 / 595) * 165
= $ 904
FIFO Basis :
Cost on FIFO Basis = 165 Units * $ 6
= $ 990
LIFO Basis :
Cost on LIFO Basis = (155 Units * $ 4) + ( 10 Units * $ 6)
= $ 680

Question No. 1-A simply supported rectangular beam 400 mm wide having an effective depth of 700 mm carries a superimposed dead load of 40 KN/m and a service live load of 50 KN/m over a 8 m clear span. Using fc’ = 21 MPa and fy = 420 MPa, Design the web reinforcement.
QUESTION 4 A beam of rectangular cross section 200 x 400 mm, is pre-stressed with force of 1 500 kN applied at 150 mm from the bottom edge of the beam, as shown on the Figure below. Calculate the magnitude of the uniformly distributed load (UDL), so that the resultant stress at the bottom edge of the beam is zero (0). 1500 kN 1500 kN> 12 m
Two identical converging lenses of focal length 100 mm are placed 400 mm apart, and an object 40 mm tall is placed 230 mm to the left of the left lens. Part B Is the image formed by the right lens inverted or upright?

Question 3 (a) Water flows through a horizontal pipeline of constant 400 mm diameter in a water treatment plant. The pipe bends through a 70° angle. In order to design a thrust block for the bend, calculate the magnitude and line of action of the force exerted by the water on the pipe. The discharge through the pipe is 0.4 m/s. The water pressure at the inlet is equivalent to 22 m head of water. [10 marks] (b) Oil of...
COCl2 (g) ⇌ CO (g) + Cl2 (g) K = 8.3 x 10-4 at 360 °C; ΔHo rxn = 109.5 kJ/mol Initially, 2.0 moles of CoCl2 were placed in an empty 1.0 L container at 360 °C. When the system reached equilibrium, what was the equilibrium concentration of Cl2? b. After the system reached equilibrium, 0.5 mol of CO were added into the container and the temperature was increased to 500 °C. When the system re-established equilibrium, what was the...
E Question-4 1.2 m 04=0 D Pipe 40-mm inside diameter 1.8 m Figure shows a siphon that is used to draw water from a swimming pool. The pipe that makes up the siphon has an inside diameter of 40 mm and terminates with a 25-mm diameter nozzle. Assuming that there are no energy losses in the system, calculate the volume flow rate through the siphon and the pressure at points B-E. 25-mm diameter 1.2 m Pp=0 Question - 5
