1)  

 A marriage party of 122 people require 73 kg vegitables. What is the requirement if 217 people turn up for the marriage

Answer: 130


SOLUTION 1 :

Given:

No of people weight of vegitables
    122  (x)        73
    217   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          122217    =   73a

                   a       =   (73x 217) / 122

                            =     15841122

                           =   130
