 Divya said: (Sep 28, 2015) Description please.

 Sudeep said: (Nov 16, 2015) Correct answer is 3/4. C = 0; D = 0. Therefore, (qf)cir/(qf)sq = 0.3yBNq/0.4yBNq. = 3/4.

 Shubham said: (Jul 16, 2016) Yeah. The Correct answer is 3/4.

 Priyanka said: (Mar 25, 2017) The correct answer is A.

 Swastik said: (Sep 4, 2017) Correct answer is A.

 Roy said: (Nov 26, 2017) It's 0.6/0.4=1.5.

 Ietakshay said: (Jul 31, 2018) Given Ans 1.3 is correct. Ratio = strength of circular section / Strength of Square section. If We assumed Side or Dia. Is 4 cm. And Load P is the same, Then Ratio of ultimate stresses of circular to the square is; = (P/12.56) / (P/16). = P .16/P. 12.56. = 1.3.

 Mohd Tariq said: (Jan 4, 2019) The Correct answer is 3/4.

 Jaydev Kumar Saha said: (Jan 9, 2019) Yes, agree the Correct answer is A.

 Bhutan said: (Jun 8, 2019) Option A, 3/4 is correct.

 Bhutan said: (Jun 19, 2019) The Correct option is A.

 Purushottam said: (Feb 5, 2020) Correct option B & D. 4/3 = 1.3.

 Rand said: (Aug 21, 2020) What if its cohesion soil? any difference? Explain me.

 Narayan Saha said: (Dec 6, 2020) The Correct answer will be option A.

 Santosh said: (Dec 24, 2020) 3/4 is the right answer.

 Mahesh Sin said: (Sep 30, 2021) Area of circular footing = π/4 d2. = 0.785 d2. Area of square = d2(because d=l). Bearing capacity = load/area. Circular = load/0.785d2. Square. = load/d2. Ratio = load/0.785d2*d2/load. = 1/0.785, = 1.27. = 1.30.
