in what time will the simple interest on rupees 400 at 10% per annum be the same and the sum of 1000 rupees for 4 years at 4% per annum​

plz tell correct answer​

Answer 1

$here$

T=4 year

R=4%

$since \: smple \: interest \: on \:$

1000=(1000×4×4)/100=160rs

$now \: simple \: intrest \:$

p=Rs 400

R=10%

then T=(100×SI)/p×R

=(100×160)/(400×10)

=4 yr
