 [A]. 5 days [B]. 7 days [C]. 10 days [D]. 14 days [E]. 21 days

Explanation:

No answer description available for this question.

 Datta said: (Mar 5, 2015) 7 days for beam soffits. 14 days for slab of span 4.6m & more. 21 days for bottom beam over 6m span.

 Darshan said: (Jul 5, 2016) 7 days for beam formwork. 7days for removing props of a slab of span 4.6m below and above 4.6 m is 14 days. Similarly for a span of 6 m below for beam is 14 days and above 6 m for props removal of the beam is 21 days.

 Siddhant said: (Jan 14, 2017) I think it should be 14 days.

 Oussama Sahnoune said: (Jun 19, 2017) 2l + 2 = 4 * 2 + 2 = 10. I think 10 days.

 Akshay Patidar said: (Jun 7, 2018) It gives length and breadth that means clearly talking about slab. So, the correct answer is 7days (According to RCC code).

 Sagar Rathor said: (Sep 16, 2019) According to IS code 456. Props to the slab. 1) Spanning up to 4.5m --> 7days. 2) Spanning over 4.5m --> 14 days. So for the longer span of 4m * 5m slab --> 14 days.

 Subrat Kumar Nahak said: (Nov 27, 2019) yes the ans should be 14 days...as per the data was mentioned in IS code...

 Abbas Khan said: (Sep 2, 2021) (4+5)/2 = 4.5 So, the span is not over from 4.5. That's why option B is the correct option.
