Hello Apoorva! 

Let free luggage be f and excess luggage charge p/kg  

Raja has x kg and Praja has (60 - x) kg 

( x - f) p = 1200 

( 60 - x - f ) p = 2400 

and ( 60 - f) p = 5400 

Now divide them to get 3x - f = 60 ..... (1) 

and 9x - 7f = 120 ...... (2) 

from (1) and (2) 

x = 25 , f = 15 . 

33. Praja has 60 - 25 = 35 kg .  (option D. ) 

34.  15 kg . ( Option B )

If you have two identical balls , one heavier than the other , you can easily determine which is heavier by putting them on opposite pans of a balance scale . If there are four balls , all the same weight except for one heavier one , you can find the heavier one in two weighings.

Suppose you have nine identical balls, one of which is heavier than the eight others . What is the smallest number of weighings needed for positively identifying the odd ball ?



2 or 3?
