1)  

 A marriage party of 116 people require 74 kg vegitables. What is the requirement if 248 people turn up for the marriage

Answer: 158


SOLUTION 1 :

Given:

No of people weight of vegitables
    116  (x)        74
    248   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          116248    =   74a

                   a       =   (74x 248) / 116

                            =     18352116

                           =   158

248 people require  158 kg of vegitables for the marriage
