Statement : One of the problems facing the food processing industry is the irregular supply of raw material. The producers of raw material are not getting a reasonable price.

Courses of Action :
I. The government should regulate the supply of raw material to other industries also.
II. The government should announce an attractive package to ensure regular supply of raw material for food processing industry.

Raw material returned to stores from manufacturing department on 14th January, 50 units. The material is issued on First-in-First out method.
The value of material remaining in store on 21st January will be:
The price of raw materials has gone up by 15%, labor cost has also increased from 25% of the cost of raw material to 30% of the cost of raw material. By how much percentage should there be reduction in the usage of raw materials so as to keep the cost same?
An iron blast furnace produces hot metal containing 95% Fe. The iron ore charged into the furnace contains 95% Fe2O3 and the rest is gangue. Assume that all the iron in the ore goes to hot metal. The amount of iron ore (in kg) required for producing 1000 kg of hot metal is (Atomic weight of Fe = 56 g mol-1 and that of Fe2O3 = 160 g mol-1)
In an ideal blast furnace, the input and output are as follows:
Input:
Ore, Pure Fe2O3, no gaunge : 1357kg/THM∗
Coke, Pure C, no ash : 400 kg/THM
Blast air, dry : O2 : 293 kg/HTM, N2 : 964 KG/THM
Flux : nil
Output :
Hot metal : 5wt% C, rest iron
Slag : nil
Top gas : CO, CO2, N2
∗ THM refers ton of hot metal (liquid pig iron) ; Atomic weights: C-12, O-16, Fe-56 The amount of oxygen in CO & CO2 leaving with the top gas is . . . . . . . . kg.
Grey pig is produced when the blast furnace is not provided with sufficient fuel while the white pig is produced when the blast furnace is provided sufficiently with fuel.
Temperature of blast furnace gas emanating from blast furnace is about . . . . . . . . degree C
Explosion limit of blast furnace gas is 37 to 71% gas in gas-air mixture. It means that the blast furnace gas will explode when burnt in a confined space, if its concentration in the gas-air mixture is __________ percent.
The price of raw meterials had gone up by 15% labor cost has also increased from 25% of the cost of ras material to 30% of the cost of raw material. By how much percentage should there be reduction in the usage of raw materials so as to keep the cost same?
