I have a problem I tried to solve, but couldn't because I don't know the method to solve it and I've never come across such problem.
Here's the problem.
Where P, Q, R, S are distinct single digit natural numbers, then R=?
We need to find out the value of R, and given option are
I've tried solving it by option with newly created equation as Q²=RS/P and taking values of R from above options and other variables as distinct single digit numbers other than R, I've gone to a level after which I've got myself a lot confused and didn't know what to do. I think there is easier method to solve it which I don't know.
I'd appreciate if someone could give me a hand with this. Thanks in advance. :)
PS: The answer is c) 3
