Answer:
Time for which the principal is lent out is 7.5 years.
Step-by-step explanation:
Formula used : SI = PRT / 100
where P is principal
R is rate of interest p.a. in %
T is time in years
Given :
SI = (9/16) P
R = T
Substituting the given values in the formula, we have
(9/16) P = PR²/100
(4R)² = 900 = 30²
=> 4R = 30 => R = 7.5
Also, T =7.5
Therefore, the principal is lent out for a time period of 7.5 years.
