Answer:

Jenny age is 13 yrs & Miki is 9 yrs old.

Step-by-step explaination:

Given that Jenny is four years older than miki.

Therefore, let Miki present age = x yrs

⇒ Jenny present age = (x+4) yrs

Five years ago, Miki and Jenny age was

Miki age = (x-5) yrs

& Jenny age = (x+4-5) yrs i.e (x-1) yrs

No, it is given that five years ago jenny was twice as old as miki

∴ (x-1) = 2(x-5)

⇒ x-1 = 2x-10

⇒ x = 10-1 = 9

Hence, Miki present age = x yrs = 9 yrs

⇒ Jenny present age = (x+4) yrs = 9+4 = 13 yrs

If Jenny was twice Miki's age, and also, she is 4 years old, it means that Jenny was 8 years old and Miki was 4 years old. As this happened five years ago, then currently: Jenny = 8 + 5 = 13 years and Miki = 4 + 5 = 9 years.
Finally, Jenny is 13 years old and Miki is 9 years old.

Data Computer Systems is considering a project that has the following cash flow data. What is the project's IRR? Note that a pro

Snowcat [4.5K]

Answer:

13%

Explanation:

To solve for the IRR we first need the formula

$NPV=\sum_0^3 (\frac{CF_t}{(1+r)^t}$

where NPV is the net present value, $CF_t$ is the cash flow in period t, and r is the IRR (internal rate of return)

Solving this polynomial can be quite cumbersome. Thankfully excel has a built in function that we can take advantage of call IRR

As shown in the screen shot we write the cash flow, with the first one with the negative sign. Then we call the IRR function selecting the cells with our Cash Flow values and excel will return the IRR. In this case is 13%

Present value of annuity = Annuity * ( 1 - (1 + rate)^-number of periods) / rate

= 9.45 * ( 1 - (1 + 10.7%)⁻¹³) / 10.7%

= 9.45 * 6.8529386295
