b) Write a note on pattern
allowances 5
SECTION II
2
a) Explain avoidable and unavoidable errors with
example 5
b) Define standard cost and mention the advantages of
standard
cost 5
c) State the advantages of efficient
costing 5
3 a) Draw the Block diagram to show
the relationship between elements and
Components of cost
5
b) A small firm is producing 100 pens per day. The direct material
cost is found to be
Rs 160, direct labour cost is Rs 200 and factory overheads are Rs 250. If the
selling
on cost is 40% of the factory cost, what must be the selling price of each
pen
to realise a
profit of 14.6% of the selling price? 10
4
a) State the causes for
depreciation 5
b) An industrial plant with an initial value of Rs 2, 00,000
and salvage value of
Rs 20,000 at the end of 20 years were sold for Rs 1, 45,000 at the 10 years.
What is the profit or loss, if sinking fund depreciation at 8% compounded
annually was
adopted? 10
SECTION III
5
a) Mention the procedure for estimation of material
cost.
5
b) Find out the weight of the 10 mild steel spindles as per
the dimensions given
in figure. Calculate the weight of scrap with their turned out from a mild
steel
rod of 25 mm diameter and facing and parting off allowances can be taken
as 1 mm and 5 mm respectively. Assume that 15 mm length of rod is required
for grip in the chuck. Density of m s is 7.8
gm/cc.
10
6 a) Define cutting
speed and depth of cut 5
b) Find the
time required to turn a 60 mm dia rod to the dimensions shown
in the fig. Take cutting speed as 20m/min feed 1.2 mm .All cuts are 3mm
deep 10
7 a)
Explain any two sheet metal joints with simple
sketches.
5
b) A container open on one side of size 0.5X0.5x1m height is to be
made from
plates of 6 mm thickness. Take density of plate metal as 8 gm/cc and joints are
to be welded. Estimate the cost of the container from the following
data.
Cost of the plate = 30/kg
Sheet metal scrap = 5% of material
Cost of labour = 25% of material cost
Cost of welding material = Rs 20 / metre of
weld
10
SECTION IV
8
a) Define working capital and mention the factors
affecting working
capital 5
b) Find the cost of 2000 C I pulleys as
shown in the fig. Its surfaces are to be
machined after casting. The pattern is supplied by the customer. Following data
is to be used
.
Cost of metal = Rs 20/kg
Moulds prepared by each worker = 20
Melting charges = 20% of metal cost
Machining allowance on each side = 2
mm
Wages of
each moulder = Rs 160 / day
Density of cast iron = 7.2
gm/cc
Overhead charges = 25% of metal
cost
10
9 a) Define
wages and mention the types of
wages.
5
b) Define incentives and explain different types of incentives with
examples
5
c) Mention the characteristics of a good wage and incentive system. 5
10 a) Mention the steps
involved in project
planning
5
b) Draw a diagram to illustrate the breakeven point
5
c) Fixed costs in a factory is Rs 10000/ year and variable costs are Rs
2.00/ unit
and selling price is Rs 6.00 / unit. Calculate the
BEP
