Answer:
The first worker complete the job in 25 days himself
The second worker complete the job in 20 days himself
Explanation:
r1= rate of work done by first worker
r2=rate of work done by second worker
W= total work done
t days= time taken by the 1st worker to complete the job
r1(t)=W
r1=W/t (1)
Then the time taken by the 2nd worker to complete the job is t-5 days.
r2(t−5)=W
r2=W/(t−5) (2)
If 1st worker do the job for 1 hour and then both the worker do the job for 4 hours and 40% work is done, So
r1(1)+(r1+r2)(4)=4W/10
r1+4r1+4r2=4W/10
5r1+4r2=4W/10 (3)
Substitute equation 1 and 2 into (3)
5W/t+4{W/(t−5)}=4W/10
Multiply through by 10(t-5)
5/t+4/t−5=4/10
5(10)(t−5)+4(10)(t)=4(t−5)(t)
50t−250+40t=4t^2−20t
4t^2−110t+250=0
Solving the above quadratic equation using factorization method
4t^2−100t−10t+250=0
4t(t−25)−10(t−25)=0
(t−25)(4t−10)=0
t=25 or t=2.5
2.5 can't be the answer because if we take 2.5 days in which 1st worker completes the work, then the second worker will complete the work in -2.5days which is wrong.
The first worker completes the job in 25 days by himself and the second worker completes the job in 20 days by himself.
Answer:
- The adjustment causes an increase in an asset account and an increase in a revenue account.
- Accounts receivable is usually increased when accruing revenues.
- They refer to revenues that are earned in a period, but have not been received and are unrecorded.
- They refer to earnings which have been earned but not yet billed.
Explanation:
Accrued revenue refers to cash earned for selling a good or delivering a service yet the cash has not been received and the transaction was not recorded in the books as revenue. This means that the cash has been earned but it has not been billed to the customer it was earned from.
When the books are being adjusted for this, the accounts receivable - which is an asset account - will increase to show that cash is owed. Revenue will also increase as this was cash earned from delivering a good or service.
Answer:
Work specialization.
Explanation:
Is an organizational structure. Work specialization is the degree to which task in the organization are divided into separate jobs with each step completed by a different person.
The theory of Work specialization is: breaking down large jobs into smaller components, and delegating different parts to individual workers.
Most managers today see work specialization as an important organizing mechanism as it helps employees to be more efficient.
Saves time by eliminating the need to switch between jobs.
Answer:
Assuming that the bonds are sold at par (no discount or premium), the annual coupon payments should be:
year 1 = 850,000 rubles, equal to $27,200
year 2 = 850,000 rubles, equal to $28,900
year 3 = 850,000 rubles, equal to $29,750
plus the face value of 5,000,000 rubles equal to $175,000
The company received 5,000,000 rubles today equal to $150,000
using an excel spreadsheet:
-150,000
27,200
28,900
204,750
and the IRR function, the cost of financing is 23.39%
