1)  

 A marriage party of 129 people require 60 kg vegitables. What is the requirement if 224 people turn up for the marriage

Answer: 104


SOLUTION 1 :

Given:

No of people weight of vegitables
    129  (x)        60
    224   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          129224    =   60a

                   a       =   (60x 224) / 129

                            =     13440129

                           =   104

224 people require  104 kg of vegitables for the marriage
