There are n urns and m balls. If we put 3 balls in each urn 3 balls will be excess. If we put 4 balls in each urn 1 urn will be excess. Find no. of Urns (or) Balls?

• urn=2
  ball=9
  first condition
  
  2urn * 3 ball +3=total ball(9).
  
  
  second case
  
  2urn * 4 ball +1= total ball(9).
  
  so that
  urn=2
  ball=9

• 7 Urns & 24 Balls.
  Let, n = No. of Urns ; m = No. of balls
  3n+3 = m---------->(1)
  4(n-1)= m---------->(2)
  =>4n-4 = 3n+3;
  =>4n-3n= 4+3
  n = 7
  Put n=7 in eqn(1)
  => 3(7)+3 = m
  21+3 = m
  m=24;
