I had been asked this question in an international level competition.

Asked question is from Estimate of Single & Double Room Building topic in portion Methods of Building Estimate & Estimate of Building of Civil Engineering Drawing

Answer 1

Right answer is (d) Earthwork, concrete work, brick work, plastering, water supply and steel work

Easy explanation: This method is suitable for walls of similar cross sections. Here the total centre line length is multiplied by breadth and depth of respective item to get the total quantity at a time. When cross walls or partitions or verandah walls join with main wall, the centre line length gets reduced by half of breadth for each junction. Such junction or joints are studied carefully while calculating total centre line length. The estimates prepared by this method are most accurate and quick.
