Question

if the simple interest on Rs. 10,000 /- for 2 years is RS.1800/- find the rate of simple interest​

Answer 1

P= 10000

T = 2

Interest amount = 1800

To find the rate of interest (R)

Solution,

S.I. = PRT/100

1800 = 10000 x R x 2/100

180000 = 20000R

R = 180000/20000

R = 9%

Therefore, the rate of interest is 9%.

Answer 2

Answer:

The rate of interest will be 9%

Step-by-step explanation:

Here the principal is given to be Rs. 10000

simple interest = 1800

time = 2 years

We have to find the rate of interest

simple interest = (p × r × t) /100

1800 = (10000 × r × 2)/100

1800 = 200 × r

r = 1800/200

r = 9

rate of interest = 9%
