Question

if the simple interest on a certain sum for 1st year is rs 200 then simple interest at the same rate for 3rd year is

​

Answer 1

Step-by-step explanation:

Answer:

SI for 3 years 225

SI for one year= 225/3 = 75

SI AND CI FOR FIRST YEAR IS SAME

therefore= for the first year SI = CI= 75

IF WE CALCULATE CI FOR 2 YEARS THEN

FOR FIRST YEAR CI= 75

FOR SECOND YEAR CI = 75 + CI FOR SECOND YEAR + CI ON CI OF FIRST YEAR = 75 + 75 + 3

3 is 4 % of 75 hence the interest rate is 4 %

The SI for 1 year = 75 (225/3)

interst rate = 4 %

hence by calculation we get principle = 1875
