Question

If A={8,16,24,32} and B={5,25,125} and  R is relation defined from A to B such that aRb means a<b for all aA,bB and (a,b)R, then R= ___.


  1. R={(8,25),(8,125),(16,25),(16,125),(24,25),(24,125),(32,125)}.

  2. R={(16,25),(16,125),(24,5),(24,25),(24,125),(32,25),(32,125)}

  3. R={(8,25),(8,125),(8,5),(16,25),(24,25),(32,5),(32,25)}

  4. R={(16,5),(16,125),(16,25),(24,25),(24,5),(24,125),(32,25)}


Solution

The correct option is A

R={(8,25),(8,125),(16,25),(16,125),(24,25),(24,125),(32,125)}.


R is relation defined from A to B such that aRb means a<b for all aA,bB and (a,b)R.
Then, R={(8,25),(8,125),(16,25),(16,125),(24,25),(24,125),(32,125)}.
