1.	Rat-trap bond masonry requires _________ less mortar.(a) 10%(b) 50%(c) 40%(d) 20%This question was posed to me during an interview.Question is from Cost Effective Construction Techniques in chapter Building Construction of Basic Civil Engineering
Answer» The correct answer is (c) 40% For explanation I would say: Rat-trap bond masonry is a TECHNIQUE where bricks are LAID on their edges. Hence approximately 25% less bricks and 40% less MORTAR is used compared to conventional ONE.
