Answer 1

i=PTR÷100
100=p*1*4÷100
100=p*1÷25
p=2500

Answer 2

Answer:2500 rupees

Step-by-step explanation:

given that

t=1 year

r=4 %

i=100 rs.

let principal is x rupees.

as we know

$i=\frac{p*t*r}{100}\\\\100=\frac{x*4*1}{100}\\\\x=2500$

so by investing 2500 rs. at 4%interest gives 100 rupees yearly.
