0.80x = 32
x = 32/0.80
x = 40......so 80% of 40 is 32
Standard: 203
Expanded: 200+3
Something you should know. A ratio is comparing two numbers. Anyway, the ratio is 12:8, remember to put it the order as it is listed. I hope this helps.
Principal = $15000
Amount = $16099.44
Rat of interest = r
Time = 2 years
Then
A = P(1 + r)^t
16099.44 = 15000 (1 + r)^2
(1 + r)^2 = 1.073
(1 + r)^2 = (1.036)^2
Then
1 + r = 1.036
r = 1.036 - 1
= 0.036
= 0.036/100
= 3.6%
From the above deduction, it can be easily concluded that the correct option among all the options that are given in the question is the second option.
