Question

the simple interest on rs5000 for 6month is 125.find the annual rate of interest​

Answer 1

Answer:

Step-by-step explanation:

SI = P*R*T/100

125= 5000*R*6/100

R=5/12 this is for 6months

now r per annum = 2*5/12=5/6

Answer 2

Simple interest for 6 Month = 125 Rs

Now we know that

Simple interest = +Principal x rate x time)/100

Principal = 5000 Rs

Time = 6 months i.e 1/2 year

Simple Interest = 125 Rs

Put all these values in formula

we get

125 = (5000 x Rate x 1/2)/100

After solving rate = 5 % per annum

SECOND METHOD

It is a short method.

Simple interest for 1 year = 125 x 2 = 250 Rs

now find 250 is how much percent of 5000.

i.e 5 Percent.

if you are a class X or XII Student it's ok if you don't understand second method.

Use First method.
