1)  

 A marriage party of 140 people require 69 kg vegitables. What is the requirement if 217 people turn up for the marriage

Answer: 107


SOLUTION 1 :

Given:

No of people weight of vegitables
    140  (x)        69
    217   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          140217    =   69a

                   a       =   (69x 217) / 140

                            =     14973140

                           =   107

217 people require  107 kg of vegitables for the marriage
