Question

find the time( in years) in which the simple interest on₹ 900 at 6% per annum is equal to the
simple interest on ₹ 540 for 8 years at 5% per annum
​

Answer 1

Answer:

p=540

t=8y

r=5%

si=ptr/100

=540×8×5/100

=216

si=216

p=900

r=6%

t=?

si=ptr/100

216=900×x×6/100

216=54x

x=4

time=4 years

Answer 2

Answer:

principal = 540rs.

rate = 5%

time = 8 yrs.

simple Intrest = (P*R*T)/100

=(540*5*8)/100

=(54*5*8)/10

=2160/10

=216rs.

principal = 900rs.

rate = 6%

let time = x

simple Intrest = (P*R*T)/100

= 216rs.

AtoQ

216=(900*6*x)/100

216=(9*6*x)

216=54x

216/54=x

4=x

so the time is 4 years.
