Answer:

\frac{1}{17}

Explanation:

Let D be the event that the lost card is a diamond

and D' be the event that the lost card is a non diamond

Therefore,

P(D) = \frac{13}{52} = 0.25

P(D') = \frac{39}{52} = 0.75

Now,

Event that the cards picked up are both diamonds = A

Thus,

P( A | D) = \frac{12}{51 }\times\frac{11}{50}               [ As One Diamond Card is lost ]

And,

P(A | D') = \frac{13}{51}\times\frac{12}{50}                [ As One Non-Diamond card is lost ]

Therefore,

P(A) = P(D) × P(A | D) + P(D') × P( A | D')  

= 0.25 × \frac{12}{51 }\times\frac{11}{50}  + 0.75 ×  \frac{13}{51}\times\frac{12}{50}

= \frac{1}{17}

notka56 [123]

Answer:

Break even sales will be $2700

So option (b) will be correct option

Explanation:

We have given fixed cost = $1400

Sells per unit = $27 each

And variable cost per unit = $13 each

So contribution margin ratio =\frac{sales\ per\ unit-variable\ cost\ perunit}{sales\ per\ unit}=\frac{27-13}{27}=0.5185

We know that break even sales is given by

Break even sales =\frac{fixed\ cost}{contribution\ margin\ ratio}=\frac{1400}{0.5185}=$2700

So option (b) will be correct answer

3. If a balance sheet were prepared for Pala Medical Co. on June 30, 20Y1 the amount to be reported as cask is $166,436  

Explanation:

1. The balance shown by the bank statement seldom agree with the balance shown by the cash book, bank reconciliation statement is usually drawn up to  agree the balance shown by the bank statement with the balance shown by the cash book.

In this question:

a. Check  outstanding of $19,427 are checks issued to creditors which where not presented for payment. generally known as unpresented checks.

b. The receipts of $12,300 recorded in Pala Medical Co. cash book was not credited by the bank, this will obviously cause a disagreement between the bank statement and the cash book at month end.

c. The amount of $26,500 recorded in the bank statement must be reported correctly the the cash book and the relevant ledger by debiting the cash book by the total receipt of $26,500 and crediting investment and with $25,000 and crediting the interest elements to interest income account.

d. The wrong recording of $400 instead of $4000 must be corrected by reversing the initial entry. this is done by debiting Cash book with $400 and crediting Creditor account - Skyline Supply Co. with $400   and recording the correct entry by debiting Creditor account - Skyline Supply Co. with $4000 and crediting cash book by $4000.

e. The check of $195 is recorded correctly already in the cash book, it is the bank to pass the necessary entry but it will only enter the company cash book.

f. Bank service charge should be recorded by debiting bank charges with $55 and crediting cash book with $55
