i was just going to give the same answer

oh sorry melody ill do it again!

my answer is funny!

106 is divisible by 2 , 106  is divisible by 1, 106 is divisible by 106......

Well that's the question I was struggling with but then my teacher told me that in the question it would be given that the sum has to be compounded annually or half yearly or by using simple interest ! It would all be given like how much will $45 be after two years at the rate of 5% compounded annually? So like that it would be given and you just have to use the formula with a sprinkle of your brain!

ok!So just enter 272/165 in the on-site calculator on the homepage and hit enter and youll get your answer , and add a cm to it too!

Welcome...Melody!

I think by that you mean 5^-2 so 

5^-2 = 1/5^2 = 1/25

That is 35.5 as a decimal!

See ill tell you! It's really easy! Every number is bro g multiplied by 3 like 3 by 3 is 9 , 9 by 3 is 27 and 27 by 3 is 81 and so on so to get te ninth term just keep on multiplying the numbers by 3 , multiply 243 by 3 and what you get by3 and there you go with your ninth number!

here is it....first of all whats the formula for finding SI (simple interest)?

it is  $$\frac{p*r*t}{100}$$  

so in this we will place everything int heir place and solve!

now SI= Amount - Principal 

so SI = 688 - 500

therefore SI =188

now lets place everything

Lets take rate to be 'r'

$$188=\frac{500*r*4}{100}$$

now divide or cut 500 by 100 and multiply by 4

so that gives us

$$188=20r$$

now divide 20 by 188 to get r

$$\frac{188}{20}=r$$

divde!

$$\frac{47}{5}=r$$

$$9.5=r$$

so the rate is 9.5%

to check the answer you can put 9.5 in rate's place and get 188...its correct!

any doubt?
