Question

What is the rate R of simple interest if a
sum
of Rs.10,000 accumulates to
Rs.15,000 in 5 years?




option
R = 5 p.c.p.a
R = 7.5 p.c.p.a
R = 20 p.c.p.a
R = 10 p.c.p.a​

Answer 1

Answer:

Given,

P=10000

A=15000

T=5 years

So,

S.I=15000-10000=5000

A/C

S.I=P*R*T/100

5000=10000*R*5/100

5000=500R

5000/500=R

10=R

THEREFORE,

RATE OF INTEREST=10%p.a.
