The question is incomplete. The snapshot of a system was not added. See below the remaining part of the question and the answers.

Allocation Max Available Available

ABCD ABCD ABCD

PO 2001 4212 3321

P1 31 21 5252

P2 2103 2316

P3 1312 1424

P4 1432 3665

Answer:

(a) safe sequence is P0 , P3, P4, P1, P2

(b) The request can be granted

Explanation:

Need Matrix

Need [i, j] = Max [i, j] – Allocation [i, j]

A B C D

P0 2 2 1 1

P1 2 1 3 1

P2 0 2 1 3

P3 0 1 1 2

P4 2 2 3 3

Available = (3 3 2 1)

1. Need(P0) < Available so, P0 can take all resources

Available = (3 3 2 1) + (2 0 0 1) (Allocation of P0) = (5 3 2 2)

2. Need(P3)<Available so, P3 will go next

Available = (5 3 2 2) + (1 3 1 2) = (6 6 3 4)

Like wise next P4, P1, P2 will get resources.

So safe sequence is P0 , P3, P4, P1, P2

Request from P1 is (1 1 0 0) and Available is (3 3 2 1)

As request(P1) < Available, we can grant request

Request from P4 is (0 0 2 0) and Available is (3 3 2 1)

As request(P4) < Available, we can grant request

Answer:

Answer: (b) As request(P1) < Available, we can grant request

Explanation:

Need Matrix

Need [i, j] = Max [i, j] – Allocation [i, j]

A B C D

P0 2 2 1 1

P1 2 1 3 1

P2 0 2 1 3

P3 0 1 1 2

P4 2 2 3 3

Available = (3 3 2 1)

1. Need(P0) < Available so, P0 can take all resources

Available = (3 3 2 1) + (2 0 0 1) (Allocation of P0) = (5 3 2 2)

2. Need(P3)<Available so, P3 will go next

Available = (5 3 2 2) + (1 3 1 2) = (6 6 3 4)

Like wise next P4, P1, P2 will get resources.

So safe sequence is P0 , P3, P4, P1, P2

Request from P1 is (1 1 0 0) and Available is (3 3 2 1)

As request(P1) < Available, we can grant request

Request from P4 is (0 0 2 0) and Available is (3 3 2 1)

As request (P4) < Available, we can grant request

Anni [7]

Answer:

Explanation:

given data

invests $4,000

share = 200

return = 24%

and

invests = $2000

share = 100

return = 18%

and

invest = $4,000

share = 400

return = 28%

to find out

expected return on this portfolio

solution

we know total investment is

Total investment = 4000+2000+4000

Total investment = 10000

and

Wt. of Sand Corporation shares in the total portfolio= $\frac{4000}{10000}$ = 0.4

Wt. of Water Corporation shares in the total portfolio= $\frac{2000}{10000}$ = 0.2

Wt. of Beach Corporation shares in the total portfolio= $\frac{4000}{10000}$ = 0.4

and

Expected return on the given portfolio is

Expected return = 0.4 × 24% + 0.4 × 18% + 0.4 × 28%

Expected return = 28%
