1)  

 A marriage party of 102 people require 75 kg vegitables. What is the requirement if 213 people turn up for the marriage

Answer: 157


SOLUTION 1 :

Given:

No of people weight of vegitables
    102  (x)        75
    213   (y)      (a)

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

 It is in direct variation.

So,     xy   =  constant

          102213    =   75a

                   a       =   (75x 213) / 102

                            =     15975102

                           =   157

213 people require  157 kg of vegitables for the marriage
