Question

find the compound interest on rs 3125 for 3 years if the rates of interest for the 1st year is 4% 2nd year 5% and 3rd year is 6% per annum.​

Answer 1

Your Answer is 492.25.....

Answer 2

Answer:

p = 3125

n = 1

r = 4

compound interest 1st year = 3125 + 125 = 3250

amount = 3125 × 4/100 = 125

p = 3250

n=1

r = 5

compound interest 2nd year = 3250 + 162.5 = 3412.5

amount = 3250 × 5 / 100 = 162.5

p=3412.5

n = 1

r = 6

compound interest 3rd year = 3412.5 + 204.75 = 3617.25

amount = 3412.5 × 6 / 100 = 204.75

total amount = 125 + 162.5 + 204.75 = 492.75

total CI = 10279.5
