Answer:
We should invest 9600 .
Step-by-step explanation:
Interest received in Two and a half year = 1,200
So, Interest that should be received in a year = 1200×[tex]\frac{2}{5}[/tex]
= 480
Interest rate = 5%.
Let we had invested amount X.
Thus 5 % of X we will get in a year as interest
Which is [tex]\frac{5}{100}[/tex]×X = [tex]\frac{X}{20}[/tex].
It is also equal to 480 as calculated above,
So. X = 480×20 = 9600.
Thus,
We should invest 9600 .
