The problem statement is: What annual instalment will discharge a debt of 1092 due in 3 years at 12% simple interest? Now, what I know is Simple interest =( principal* Rate per annum*Time in years)/(100) Here, R= 12℅ ,T=3 years but I don’t understand how to move forward.I am not getting the meaning of the […]

I was reading something today that was talking in terms of 10%, 100% and 1000% faster. I assumed that 10% faster means it takes 10% less time (60 seconds down to 54 seconds). If that is correct wouldn’t 100% faster mean 0 time and 1000% mean traveling back in time?

A hypothetical example: You have a 1/1000 chance of being hit by a bus when crossing the street. However, if you perform the action of crossing the street 1000 times, then your chance of being hit by a bus increases to about 60% because every time you do the action, the probability of it happening […]

If percentage points can equal decimal points, then $1.25$ should equal $125$% when multiplying $1.25$ by any number. Therefore $125$% of $0.75$ should equal $1$ if $0.75$ is also $75$% of $1$. Am I missing something super obvious here or what?! Please help. Thank you!

Tried my best with the title. Ok, earlier while I was on break from work (I have low level math, and want to be more fond of mathematics) I work retail, and 20% of taxes are taken out, and I am wanting to find out how much I made before 20% is taken out. So […]
