Question

the simple interest on a sum of five years is one fourth of sum . what is the rate of interest per annum​

Answer 1

Answer:

5%

Step-by-step explanation:

lets take the sum as 100

for 5 years the intrest is 25 which is 1/4 of sum

now you know formula for simple intrest

si= (principle * no of years * rate of intrest)/100

SI FOR 5 YRS

25=100*5*r/100

25=500*r/100

25=5*r

r=25/5

therefore r=5%.
