Question

How long does it take for rs 25000 at a simple interst at the rate of 5% to become rs 30000

Answer 1

We k/w
T=SI×100/P×R
=5000×100/25000×5
Solving it.We get
=100/25
=4 years

Answer 2

simple interest(S.I)=p*r*n/100

given,

p=25000,r=5%

assume n=1year

S.I=(25000*5*1)/100

 S.I =1250

For 1 year principle=25000+1250=26250

for 4 year =25000+5000=30000.

therefore Rs 25000 at 5% takes 4 years to Rs 30000.
