1)  

 A marriage party of 122 people require 69 kg vegitables. What is the requirement if 238 people turn up for the marriage

Answer: 135


SOLUTION 1 :

Given:

No of people weight of vegitables
    122  (x)        69
    238   (y)      (a)

As the No of people increases, weight of the vegitable also increases .

 It is in direct variation.

So,     xy   =  constant

          122238    =   69a

                   a       =   (69x 238) / 122

                            =     16422122

                           =   135

238 people require  135 kg of vegitables for the marriage
