Let Raj be 3 years older than Ravi and Hema be two years younger than Ravi. Raj is three times as old as Rahul
who is Hema's brother. The ratio of the ages of Hema and Her brother is 3:2. Find by how much percentage Raj's age
is more than Hema's when Raj will be 20 years old.
a) 33.33
b) 40
c) 60

• The equations formed :
  
  RAJ = 3 + RAVI
  
  RAVI = 2+ HEMA i.e
  RAJ = 5 + HEMA --- This is the only equation that is needed to find the solution.
  Other details and ratios are just useless.
  
  Since , RAJ is 5 years elder to HEMA . So, when RAJ is 20 ; HEMA = 15
  
  % RAJ more than HEMA = (RAJ / HEMA ) * 100
  => 20 /15 * 100 => 133.33 .
  Therefore an increase by 33.33 %
  
  Thanks !!
