Question

In what time S.I. on Rs.500 at the rate 3% p.a. is same as the S.I. on Rs 900 for two years at the rate 5% p.a.?

Answer 1

S.I. = I*R*T

In the first case,
S.I. = 500*3*T = 1500T

In the second case,
S.I. = 900*5*2 = 9000

It is given that the S.I. are equal

So, 1500T = 9000
T = 9000/1500
T = 6 years
