In case of discount:

Let income amount = 100, time = 1.5 years, and rate =20 %.
Formula:
A = P(1+rt)
A =P+I
by putting vale in the above formula we get the value that is = 76.92, thus method A will give 76.92 value.
If we calculate discount then the formula is:
P = M(1-rt)
M = 100 rate and time is same as above.

Thus Method B will give the value that is 70
calculating ratio value:
