Seven friends Akil, Nikil, Samuel, Manish, Praveen, Arun, and Frank went for shopping to different showrooms – Levi’s, Allen solly, Adidas, Puma, Denim, Basics and Woodland and bought different colours of dress – red, blue, green, yellow, pink, black and violet but not necessarily in the same order. Nikil went to Denim but did not buy yellow or pink colour dress. Samuels bought red colour dress but did not go to Allen Solly or Basics. Praveen went to Puma and bought black dress. The one who bought blue dress went to Woodland. Manish went to Levi’s, Frank likes violet colour, Akil did not go to Woodland. The one who likes yellow colour went to allensolly.
