Question

calculate the si unit on ₹8000 for 2½ years at 4½% p.a​

Answer 1

here is your answer:

$principal \: (p) = rs. \: 8000 \\ rate \:( r) = 4 \frac{1}{2} \% p.a= \frac{9}{2}\%p.a \\ time \: ( t)= 2 \frac{1}{2}years = \frac{5}{2}years \\ therefore \: s.i = \frac{p \times r \times t}{100} \\ = rs.( \frac{8000 \times 9 \times 5}{100 \times 2 \times 2}) \\ =rs . (20 \times 9 \times 5) = rs.900$
