(a)
(i) Zero Based Budget: This implies
starting the budget from zero situation and
justifying each segment of the budget rather than merely adding to
historical budgets or actual .
(ii)
Flexible Budget: This is one designed to adjust the budget cost levels to suit
the level of activity actually attained.
(iii) Budget Committee: This is normally chaired
by the Chief Executive of the organisation, with departmental heads or senior
managers as members.

(I) Activity Ratio = Standard
Hours x 100
Budgeted Hours 1
= 113,583 x 100

= 94.1%
This means that the actual level of production
is less than budgeted level by 5.9%.
(ii) Efficiency Ratio = Standard Hours x 100
Actual Hours 1
= 113,583 x 100
100,000 1
= 113.583
= 114%
This means that the actual level
of production was achieved in less time than standard by working at a rate which
was nearly 14 % above normal level of efficiency.
(iii) Capacity Ratio = Actual Hours worked x 100
Budgeted Hours 1
=
100,000 x 100

(c ) Comments
Material Price
Variance
Concentrated juice gave a favourable variance while
Carbonated water gave adverse. It could be due to any of the following:
i. Unexpected
change in the price of materials.
ii. Faulty determination of standard price.
Material Usage
Variance
Concentrated juice gave an adverse variance while
Carbonated water gave an almost compensating figure of favourable variance.
Considered in total, the net effect could be misleading, but considered
separately, we may be able to discover the following:
i. The use of
employees with varying levels of experience in production leading to either
minimum
or excess wastages.
ii. The use of either better or inferior quality
material.
iii. The condition of the machinery used in
production would have an effect on materials consumption and waste generation.
Wage Rate
Variance
The adverse variance recorded here may be due to paying
higher rates than anticipated, or the use of skilled labour where unskilled
labour was earlier planned for.
Labour
Efficiency Variance
This gave a favourable variance, if skilled labour
was used instead of unskilled, the favourable efficiency variance could be the
result.

also include the cost of attaining 120% level of activity. Fixed costs remain
unchanged.
SUGGESTED SOLUTION
(a) Cash
budget is a summary of the company`s expected cash inflows and outflows over a
given
period of time.
(b) Four
benefits to be derived from the preparation of detailed cash budget are:
i. It
provides early signals of potential deficit or surplus in order to take
appropriate action.
ii. It
enables financial feasibility of plans to be ascertained.
iii. It indicates the financial effects of policies
within a firm.
iv. It provides a base for monitoring actual
activity. The frequent comparison of actual cash
flow with
budgeted cash flow will enable up-to-date information to be incorporated into
budget
revisions.

SUGGESTED SOLUTION
(a) Cost-Volume-Profit Analysis Technique is a
technique which determines the combined effect of both cost and revenue
function of changes in the level of activity.
It is known as Beak-Even Analysis which is used to
measure the effect on profit as a result of changes in both revenue and cost
function.
(b) The usefulness of Cost-Volume-Profit Analysis
are:
i. It is
very helpful in budget planning.
ii. It helps
in selling price and volume decisions.
iii. It can be used to determine the approximate
product mix.
iv. It can be used to quantify the effects of cost
reduction programmes.
v. It is an
effective control method which can be used on forecasting or estimating future
profits.
The following are the assumptions of
Cost-Volume-Profit Analysis:
i. Volume is
the only independent variable affecting revenue or cost function.
ii. All costs
could be categorised into either variable cost or fixed cost.
iii. There is only one product or constant mix of
product.
iv. Variable cost per unit is assumed to be
constant.
v. The fixed
cost remains unchanged.
(c ) Let F= Total Fixed Cost
C= P/V Ratio
X = Sales in naira
P/V graph has an equation given by:
Profit = CX -

Using the data for the period 1 and period 2.

2,300 =

Subtract eq.(i) from eq. (ii) , we have
1,500 = 8,000C
C = 1,500 =
0.1875

Substitute for C= 0.1875 in eq.(i), we have
800 = 30,000 (0.1875) – F

F = 5,625 – 800
