The first step is to find the CHANGE. This is done by subtracting the two values and taking the absolute value. Next step is to find the ratio of the change to the original and multiplying by 100% to make it a percentage.
So;
a) change = Ι60 - 25Ι = 35.
ratio of change to original = 35:25,
multiplying by 100% will give 35/25 × 100% = 140%.
Hence it is a 140% INCREASE.
b) change = | 30 - 66 | = 36
the ratio is 36:66
multiplying by 100% = 36/66 × 100% = 0.545454... ×100% ≈ 54.5%
Hence it is a 54.5% DECREASE.
Helpful?
I'm not really sure, because 650 marked down by 27% would be 474.5, which is close but not exact.
Hope I helped a little bit, sorry if I'm wrong.

Answer:

Step-by-step explanation:
We know that for principal amount P , time period T and rate of interest
, simple interest is given by
.
Here ,

To find : simple interest rate i.e., 
On putting values of
in formula , we get 

Now we need to round off the answer to the nearest tenth .
So, simple interest rate is % =
=
