Question

p=10000,I=900,T=9months find rate of interest​

Answer 1

Answer:

Simple Interest

Step-by-step explanation:

SI = PTR                         T=9 months = 9 years

      100                                                 12

900 = 10000 * 9 * R

            100 * 12

900 = 100 * 3 * R

                  4

900 * 4 = R

100 * 3

3*4 = R

12 = R

Thus, R = 12%

Answer 2

Answer:

rate = I × 100 / PT

p = 10000

I = 900

Time = 9 months = 9/12 = 3/4 year

900 × 100

Rate = ------------------

10000 × 3/4

= 900 × 100 × 4

----------------------

10000 × 3

= 12 %

Rate = 12 %
