Okay, the salaries you are told are in the ratio 4 to 10 to 25, which you can write as 4x to 10x to 25x.
00:16
Where that represents the actual salary.
00:19
So 4x is the salary, as is 10x and 25x.
00:24
Now, i'm going to increase the first one by your tone 30%.
00:31
So, that means i do 4x and to increase it, i times it by 1 .3, to increase by 30%, i'm doing if you like 100%, plus 30%, 1 % 1 .3%.
00:57
Now that will be 1 .3 times 4, 5 .2x.
01:08
This one here i'm going to increase by 15%.
01:13
So it's 1 .15 times 10x.
01:21
Same as before, same reasoning.
01:24
That will be equal to 11 .5x.
01:32
And this one i'm going to increase by 25%.
01:38
So it's 1 .25 times 25x.
01:45
And 1 .25 times 25 is 31 .25 x...
