  • Why don't you divide 30 divided by 6, so do 45 divided by 9? It is much easier.

      Yup. That's correct but when the questions get harder the other method makes it both clearer and easier to understand

    Sorry, I would like to know if there are ways to solve this type of variation questions:

    If x+y ∝z , when y is constant and z+x ∝y , when x is constant, then prove that, x+y+z ∝yz , where x, y, z are variables

    I feel like I'm guessing randomly every time :/

    Thanks a lot :D

      this is a second (the same) question from you. There is never a case when y isnt divisable by the x. If you have such case please share it with us.
