In this problem, we have been given information about how much money a certain person invest in certain funds, and we have also been given the returns for each fund.
00:10
And we need to calculate the weighted mean percentage return.
00:14
So what we want to find is the weighted mean, and the formula for that is summation wx divided by summation w.
00:22
Here, w represents the weights, and x represents the scores.
00:26
And in this case, we want to find the weighted mean percentage return.
00:30
So x will represent the percentage return.
00:33
So let's find this.
00:35
So summation wx.
00:37
So first of all, note that she invests 600 ,000 in fund a, which has a return of 6 .5%.
00:45
6 .5 % is 6 .5 by 100 or 0 .065.
00:50
Next, we have that she invests 500 ,000 in fund b.
00:56
The return is 4%...
