Question

if 6 : 5 = x : 10 then what will be the value of x​

Answer 1

Answer:

The sign ‘:’ here is called ‘ratio’, which is roughly the same as ‘division’. (e.g. 6:5 means ‘6 divided by 5, or 6/5.) So the whole questions actually means 18/x=6/5. Now you multiple both sides of the equation by 5x (That is you multiply 18/x by 5x and you multiply 6/5 by 5x as well), then you’ll get 18*5=90=6x. Finally, x=90/6=15. Not that difficult question.
