Answer is 9% per annum.....
5/2 years = 2.5 years
ATQ,
P = 3000
R = x
T = 4 years
Therefore,
S.I. = (P*T*R) ÷ 100
= (3000*x*4) ÷ 100
= 120x
ATQ,
P=8000
R=x
T= 2.5 years
S.I.=(P*T*R) ÷ 100
=(8000*x*2.5) ÷ 100
=200x
Given-
Total interest earned by Sonia= ₹2880
Therefore,
200x+120x=2880
320x=2880
X=16percent
Therefore,the rate of interest is 9 % per annum.
