Pricipal = ₹16000

Simple Interest = ₹252

Time = 2yrs 3 mths = 2+3\12 = 9/4 years

Now,

$</em></strong><strong><em>si \: = \: \frac{p \times r \times t}{100} \\ = > r \: = \: \frac{si \times 100}{p \times t} \\ = > r \: = \: \frac{252 \times 100 \times 4}{16000 \times 9} \\ = > r \: = \: \frac{7}{10} = 0.7\%</em></strong><strong><em>$
