1)  

 A marriage party of 102 people require 59 kg vegitables. What is the requirement if 208 people turn up for the marriage

Answer: 120


SOLUTION 1 :

Given:

No of people weight of vegitables
    102  (x)        59
    208   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          102208    =   59a

                   a       =   (59x 208) / 102

                            =     12272102

                           =   120

208 people require  120 kg of vegitables for the marriage
