Answer:

C will take 96 days alone to do the work.

Explanation:

given,

A and B work for 12 days...................(1)

B and C work for 16 days...................(2)

C and A work for  24 days...................(3)

Adding equation (1) and (2)

A + 2 B + C = \dfrac{1}{12}+\dfrac{1}{16}\\2 B + \dfrac{1}{24}=\dfrac{1}{12}+\dfrac{1}{16}\\2B =\dfrac{1}{12}+\dfrac{1}{16}-\dfrac{1}{24}\\B=\dfrac{5}{96}

from equation (2)

B+C = \dfrac{1}{16}\\\dfrac{5}{96}+C = \dfrac{1}{16}\\C=\dfrac{1}{16}-\dfrac{5}{96}\\C=\dfrac{1}{96}

hence, C will take 96 days alone to do the work.

podryga [215]

Answer:

5.85%

Explanation:

Suppose the real risk-free rate is 3.50%,  the average future inflation rate is 2.25%, and a maturity premium of 0.10% per year to maturity applies, i.e., MRP = 0.10%(t), where t is the years to maturity.  What rate of return would you expect on a 1-year Treasury security, assuming the pure expectations theory is NOT valid?   Disregard cross-product terms, i.e., if averaging is required, use the arithmetic average.

a. 5.75%

B. 5.85%

c. 5.95%

d. 6.05%

e. 6.15%

r = r* + IP + DRP + LP + MRP

r = 3.50% + 2.25% + 0 + 0 + .10% = 5.85%
