 Krish said: (Mar 10, 2014) How it is come?

 Piya said: (Jun 13, 2014) How is it come?

 Jyotitak said: (Aug 11, 2014) Is this mean that A mason can do 7.5 X 2.5= 18.75 Cum of concrete in one day ? is that true? I doubt.

 M.Karthick said: (Oct 18, 2014) Mason will do the following process, 1. C, FA, CA shifting after weighing as per Mix design. 2. Hand mixing with water as per mix design. 3. Making homogeneous mix. 4. Making level for every 2.5sqm corner. 5. Laying & levelling concrete as per level point. 6. 7.5 Sqm only is possible.

 Bharat said: (Mar 6, 2015) @Jyotitak calculation is 7.5*0.025.

 Dev said: (Apr 22, 2015) @Bharat. What is 0.025 and what is the unit?

 Tarun said: (May 28, 2015) For 100 sum, no. of Mason is 13 no. i.e for 13 Mason flooring is 100 square meter. So for 1 Mason flooring is 100/13 = 7.69 sum. So option C is the answer.

 M.Areeb said: (Jul 23, 2015) For 100 sum, no. of Mason is 13 no. i.e for 13 Mason flooring is 100 square meter. From where you confirm that it is fixed.

 Rajashekar said: (Aug 25, 2015) One per person can place the concrete floor per day 1.875 m3. = 1.875/0.25 = 7.5 M2.

 Mounika said: (Sep 13, 2015) I didn't understand. Can anyone give a clear answer please?

 Vbk said: (Nov 30, 2015) By practical experience after trial and error with an average lead and with the help of two helpers one mason can do 7.5 square meter of flooring, NOT by a single Mason.

 D.Prashanth said: (Mar 27, 2016) If one mason can do concrete flooring of 1.875 m3 per day. So, 1.875/.25 = 7.5 square meter is the correct answer.

 Paritosh said: (Jul 27, 2016) I want to know how I can confirm that 'one mason can do concrete flooring of 1.875 m3 per day?

 Pradosh Nayak said: (Aug 2, 2016) 2.5cm means 0.025M = 1.875/.025=75 sqm. How it is 7.5sqm?

 Aishwarya Rai said: (Sep 6, 2016) What is out turn?

 Pavan said: (Sep 17, 2016) Task work or out turn work both are same. The capacity of doing work by a skilled labour in the form of work per day is known as task work.

 Kesavan V said: (Oct 18, 2016) How come this answer?

 Niketan said: (Dec 25, 2016) How it come? Please explain in simple way.

 Prabagaran said: (Jan 18, 2017) It is an approximate method. It varies from city to city. A mason is completing 7.5sq m for cement concrete floor per day.

 Erarush said: (Feb 9, 2017) It's not depend on this specific values, It only depends on mason efficiency I see masons which cover 10 cum or even more than this of concrete flow.

 Ankit said: (Mar 17, 2017) .1875/.025 = 7.5sqm.

 Gawand M. said: (Jul 15, 2017) I can't understand the basic behind this. Please explain it clearly.

 Sunil Kumar Yadav said: (Jul 28, 2017) Here, .1875/.025 = 7.5.

 Satya.M said: (Aug 20, 2017) .1875/.025 = 7.5.

 Abcd said: (Oct 8, 2017) 1 : 2 : 4 concrete, 1m3 need Labour constant. Mixing concrete --------> 3.00 hour/m3. Lifting and carrying concrete --------> 1.20 hour/m3. c.compacting concrete --------> 0.80 hour/m3. d.leveling surface of concrete --------> 0.10 hour/m3. Total=(3+1.2+0.8+0.1) = 5.

 Naresh said: (Feb 22, 2018) I am not getting it. Please explain.

 Milton Shaikh said: (Mar 3, 2018) It should not understand how can do one masonry per day 1.876?

 Pritam Rajak said: (Nov 11, 2018) It means the avg floor rough casting of thickness 2.5cm, per Masson/day.

 Ravi said: (Feb 9, 2019) Can anyone please explain me to get it?

 Ravi said: (Feb 9, 2019) Can anyone please explain me to get it?

 S Raju said: (Apr 26, 2019) The value of 1.875 coming from where?

 Akshy said: (Aug 10, 2019) 1 mason 1 day work = 0.1875m^3. For 2.5cm, it will be(0.1875/0.025) = 7.5m^2.

 Jithin said: (Aug 29, 2019) Can anyone explain on brief with a reference?

 Prats said: (Sep 15, 2019) As per given building code manuals out-turn for 2.5 cm. 7.5 square metre.

 Hisham said: (Feb 22, 2020) Any reference for this?

 Dheeraj said: (Feb 25, 2020) If any one know the basic. So please explain.

 Dheeraj Kataria said: (Feb 25, 2020) Here is mistake in question. That is. 2.5cm thick cement conc. Flooring per person per day = 7.5 sq.m.
