Hello, students, this is our table showing quantity and unit price in particular years for a and b.
00:07
So let's start with our answering part, abcd.
00:11
So this must be, in the first case, we are going to calculate.
00:15
This is our item.
00:17
And this is our relative price.
00:24
So now what we can write here, this is our a part, this is our b part.
00:30
We are going to partition this to make it more clear.
00:34
So let's erase this to make it more clear.
00:39
So here, what would be our relative? so this is 7 .15 divided by, we are going to write here for this.
00:48
This must be 7 .5 multiplied by 100, which is equivalent to 95 .33, which is equivalent to 95 .33, which is equivalent to 95 .35.
01:09
Now what would be 1500 divided by so let's erase this to make it more clear 650 multiplied by 100 that is equivalent to 231 so basically if i write here for this let's connect this let's connect this so this must be so in the first question we are going to write here this must be so in the first question we are going to write here this must be in the first question we are asked about price relative so these are price relative in this particular case now if i write here for this what would be our b part now if i write here for this what is unwated aggregate if i write here for this this must be written as unwated aggregate that is equal to sigma of p of i t and this must be divided by we are going to write here sigma of p of i not this must be multiplied by 100 so basically if i write here this is 7 .15 plus if i write here for this i of 2 .11 7 .15 plus 1500 and this must be divided by 7 .1011 and this must be divided by 7...
