Hello students, we are given a question here that calculate the rate of inflation for each year from 2014 to 17.
00:08
Okay.
00:09
So we are given here that there is a year table and cpa table.
00:14
So here we are supposed to know that first of all, cpa is, sorry, rate of inflation, we can say that rate of inflation.
00:27
Okay, students, it is equal to cps.
00:30
Cpi final cpi final minus cpi initial students cpi initial then divided by cpi initial students times 100 so now as we are supposed to know that the 2013 is a base year so we will start with first term it means the rate of inflation for 2014 okay for 2014 so we can say that here rate of inflation so what we can state here it should be equal to cpi final it means the cpi in 2014 minus cpi in 2013 divided by cpi in 2013 so basically 650 minus 650 minus 600 divided by 600 times 100 okay so what we can state here it should be like 600, 15 minus 600.
01:36
It means simple 15, then divided by here, 2 zeros would be cancelled out by 2 zeros.
01:42
So it can be directly written as 6.
01:44
So 15 divided by 6.
01:46
It means 2 .5 percentage.
01:50
Okay, students.
01:51
Now we will go to the second part.
01:55
So basically for a second, it should be like for 2 ,015.
02:00
So basically rate of inflation, it can be written as the cpi of 2015 minus cpa of 2014 divided by cpi of 2014.
02:13
It means 650 minus 650.
02:16
650 minus 650 divided by 60015 times 100.
02:24
So now it should be like 35 divided by 600.
02:30
15 times 100.
02:33
Okay, so basically 35 divided by 5 comes out as equals to here 7, then 600 15 divided by 5.
02:43
What we can state it should be equal to 123.
02:48
Okay, students...
