Answer:

4 % per annum

Step-by-step explanation:

P = 468.75

r % per annum to be find

n = 1 year 8 months = 1 + 8/12 = 20/12 = 5/3 Years

Interest = 500 - 468.75 = 31.25

31.25 = 468.75 * r * (5/3) / 100

3125 * 3 = 2343.75 * r

r = 9375 / 2343.75

r = 4

chennojwalasaisindhu: it will be more helpful if u solve the questions providing formulas

amitnrw: there are two formulas used 1. interest = returned amount - invested amount and interest = investes amount * rate of interest per annum* time in years/ 100
