Question

please help me, friends. Please, I need this immediately. Please. U can say me the answer only.

The simple interest of a certain sum is 1/10 of the principal at the rate of 5% of a certain period of time. Obtain the ratio of CI and SI of the same sum at the same time and at the same rate of interest.

Answer 1

Answer:

41:40

Step-by-step explanation:

1/10 of principal equals to 10%

at a simple rate it is obtained in 10%/5%=2 years

compound interest at the same time: 100*(1+5/100)²-100%= 10.25%

CI:SI ratio will be 10.25:10 or 41:40

Hope this helps
