t = ?
si = a-p = 1050-900
si = 150₹
p = 900₹
r = 10%p.a.
si = prt /100
150 = 900×10×t/100
150 = 90t
t = 15/9
t = 5/3
t = 1complete 2 by 3 years
si = a-p = 1050-900
si = 150₹
p = 900₹
r = 10%p.a.
si = prt /100
150 = 900×10×t/100

if its simple interest,
then 1050-900 = 150 is the interest
P*R*T/100 = 150, 900*10*T/100 = 150, 15000/9000 = T ,
Ans...5/3 years
if its compounded annually,
then Amount = P (1 + r/n)^(n*t)
A = 1050, p = 900 , r = 10 n = 1(say compounded annually)
1050/900 = (1+10)^t
35/30 = (11)^t
t = 1.12 (approx)
then 1050-900 = 150 is the interest
P*R*T/100 = 150, 900*10*T/100 = 150, 15000/9000 = T ,
