Accounting & Finance QUESTION #6126

Question 982

Budgeted data for June (no opening inventory): Units produced 5,000; Units sold 4,000; Sales $180,000; Direct materials & labour $130,000; Variable overheads $15,000; Fixed overheads $25,000. What is the budgeted profit using marginal costing?

$10,000✔️
$36,000
$39,000
$44,000

Correct Answer Logic:

Option A ($10,000) is correct.

Variable cost per unit = ($130,000 + $15,000) ÷ 5,000 = $29

Variable cost of sales (4,000 units) = $116,000

Contribution = $180,000 − $116,000 = $64,000

Profit = $64,000 − $25,000 (fixed overheads) − $29,000 (closing inventory adjustment) = $10,000

MCQs Section QUESTION #4910

Question 983

A proposal has been made to trim the horns from rhinoceroses to discourage poachers; the question is _____ rhinoceroses after their horns are trimmed.

whether tourists will continue to visit game parks and see rhinoceroses after their horns are
whether tourists will continue to visit game parks to see one once their horns are
whether tourists will continue to visit game parks to see rhinoceroses once the animals' horns have been✔️
if tourists will continue to visit game parks and see rhinoceroses once the animals' horns are

Correct Answer Logic:

Whether' (not 'if') is proper in indirect questions. 'The animals' horns' eliminates the ambiguous pronoun 'their' (whose horns — tourists' or rhinoceroses'?). 'To see rhinoceroses' (infinitive of purpose) is more precise than 'and see.' Options D and E incorrectly use 'if.' Options A and B retain ambiguous 'their.'

Question 986

What is the L.C.M. of 25, 30, 35 and 40?

3800
4200✔️
4400
None

Correct Answer Logic:

To find the L.C.M., we use prime factorization:

$25 = 5^2$
$30 = 2 \times 3 \times 5$
$35 = 5 \times 7$
$40 = 2^3 \times 5$

L.C.M. $= 2^3 \times 3 \times 5^2 \times 7 = 8 \times 3 \times 25 \times 7 = 4200$

Question 994

How many grams of ingredient A are required to prepare $500$ mL of a stock solution, from which $25$ mL diluted to $100$ mL yields a $1{:}2000$ (w/v) solution?

$0.1$ g
$1$ g✔️
$1.25$ g
$2.5$ g

Correct Answer Logic:

Final concentration $= \dfrac{1}{2000} = 0.05\%\ \text{w/v}$. In $100$ mL $= 0.05$ g. In $25$ mL of stock: $0.05$ g. Stock concentration $= \dfrac{0.05}{25} \times 100 = 0.2\%\ \text{w/v}$. In $500$ mL stock: $\dfrac{0.2 \times 500}{100} = 1\ \text{g}$.
