=>SI on 2400-SI on 2000=60
=>2400 x 3 x r/100- 2000 x 3 x r/100=60
=>72r-60r=60
=>12r=60
r=5%
=>2400 x 3 x r/100- 2000 x 3 x r/100=60

Let the S.I on Rs 2400 be x
and S.I on Rs 2000 be y
x = 2400 x 3 x R/100 = 72R
y = 2000 x 3 x R/100 = 60R
A/Q,
x - y = 60
72R - 60R = 60
12R = 60
R = 5 %
Therefore the rate of interest is 5%
and S.I on Rs 2000 be y
x = 2400 x 3 x R/100 = 72R
y = 2000 x 3 x R/100 = 60R
A/Q,
x - y = 60
72R - 60R = 60
12R = 60
R = 5 %
Therefore the rate of interest is 5%
