On Rs 6000 interest = 2000 

SI = P N R /100 
2000=6000*4*r/100 
2000*100/4*6000 = r 
r=200/24 
r= 8.33 %
Interest = 700-525= 175
P=525
I=175
r=8.33% 
175= 525*N*8.33/100 
N= 175*100/525*8.33 
N=4 years

asanraja: Amount = RS. 8000

Time (T) = 4 yr; Principal (P) = RS. 6000

Simple interest (SI) = (A-P)

= Amount - Principal

= 8000 - 6000 = RS. 2000

Rate (R) = ?

According to the formula,

SI = P×R×T100

=> 2000=6000×R×4100

=> R=2000×1006000×4=253%
