Variation  If the values of two objects depend on one another, such that the increase or decrease of one object influences the value of the other object, then those two objects are referred to as being in variation.

Direct Proportion  It is said that two quantities, a and b, are in direct proportion, if

Increase in a increases the b

Decrease in a decreases the b
However, the ratio between their respective values shall be the same.

a and b will be in direct proportion if a/b = k(k is constant) or a = kb.

In such a case if b_{1}, b_{2} are the values of b corresponding to the values a_{1}, a_{2} of a respectively then, a_{1}/ b_{2} =a_{2}/b_{1}

Symbol of Proportion
We denote proportion by ‘∝'
When two quantities a and b are in proportion then they can written as a ∝ b where ∝ represents “is proportion to”.
There are two methods to solve questions related to direct proportion.
