Question

1) A sum of R.s 45,000 earns a simple interest of R.s 6,750 in 3 years . Find the rate of interest per annum.​

Answer 1

Answer:

principal=45000

rate=r%

time=3 year

simple interest=6750

Step-by-step explanation:

p×r×t/100=simple interest

45000×r×3/100=6750

450×3×r=6750

r=6750/450×3

r=675/45×3

r=675/135

r=5

rate of interest=5%
