Question

in how many years the interest will be equal to half of principal at the rate of 5% p.a ​

Answer 1

S.I.= prt/100

where p is principal,r is rate,t is time and S.I. is simple interest.

let S.I =X so p=2x

so putting values in formula

X= 2x*5*t/100

100/10= t= 10 years

Time is 10 years
