Hi, I'm trying to solve for the money-weighted average and Dietz approximation. Please give me some guidelines, thank you!

5 For each of the last six quarters, Managers L and M have provided you with the total euro value of the funds they manage, along with the quarterly contri- butions or withdrawals made by their clients. (Note: Contributions are indicated by positive numbers, withdrawals by negative numbers.)
