Answer :-
<h3>
3 years</h3>
step by step explanation:-
Let the time be x
principal = rs 8000
Amount = rs 13824
rate = 20% p.a
A = P(1+r/100)^n
13824 = 8000 ( 1 + 20/100)^n
=> 13824/8000 = (120/100)^n
=> 13824/8000 = (24/20)^n
=> (24/20)³ = (24/20)^n
=> 3 = n
=> n = 3 years
Since the word, 'of' means to multiply, whenever we see of multply the two numbers.
Then there are two ways to dothis, sicne to convert a percentage into a decimal, you devide by 100, we can either do this after we multiply or bfore, it doesn't matter so I'm going to do it after.
1. 520x100=52000/100=520
2. 20.25x3=60.75/100=.6075
3. .15x250=37.5/100=.375
4. 200x79=15800/100=158
5..3x80=24/100=.24
6. .28x50=14/100=.14

Step-by-step explanation:
x/20 = 65%/100
20 x 65 = 1300
1300 divided by 100 = 13
Im not sure if you wrote this wrong because (x+y)2 does equal x2+y2. An example would be if x equals 3 and y equals 4 (3+4)2=(3)2+(4)2 (7)2=6+8 14=14.
