(a) A project of the initial investment of $4,000 is expected to generate $2,000 and $3,000 at the end of year 1 and year 2, respectively. Sep up an equation and find the IRR of this investment (b) On 1 January 2016, a fund was valued at $200,000. On 1 May 2016, the fund increased in value to $210,000 and S30,000 of new principal was injected. On 1 November 2016, the fund value dropped to S200,000, and S50,000 was withdrawn. At the end of the year, the fund was worth $200,000. Calculate the DWR.R and the TWRR.
