SI rate = 4.5%

SI earned = ₹ 0.81

time = ??

$As \: we \: know \: that , Simple \: Interest \\ \: \: \: \: \: \: \: \: \: \: \: \: = \: \frac{p \times r \times t}{100} \: \\ \\ so, \: t = \: \frac{Simple \: Interest \times 100}{p \times r} \\ \\ so, \: t = \: \frac{0.81 \times 100}{900 \times 4.5} \: = \: 0.02 \: years$

so, in 0.02 yrs or in 7.3 days we can earn ₹ 0.81 from ₹ 900 at a rate of 4.5 SI.
