 Ankitha said: (Apr 5, 2017) Single line 4.9m width. Double. 6 m. So, 4.9 /6 = 0.82. Answer C.

 Arul Raj said: (Jun 11, 2017) L1 = xcos30°. L2 = xcos60°. L1/L2 = 1.732 = approximately equal to 2.

 Roy said: (Dec 8, 2017) 30°- 4.66 m. & 60°=5.58m. So, ratio=(4.66/5.58)==0.8.

 Subham Dutta said: (Sep 18, 2018) (5sin30+2.5sin30)/(5sin60+2.5sin60) =.577 ==.5 = A.

 Hardev Chauhan said: (Apr 22, 2019) [Lsin60° +l/2sin30°]/[Lsin30° + l/2sin60°]. (L=6). = [6sin60°+3sin30°]/[6sin30°+3sin60°], = [6.206/7.281]. = 0.85 Ans.

 Kamalesh Biswas said: (Feb 16, 2020) 30°/60°=1/2=0.5.

 A Ali said: (Dec 21, 2020) 0.8 is the correct answer.

 Kis said: (Feb 14, 2021) Yes, .8 is the correct one.

 Mir Imroz said: (Mar 13, 2021) Ratio of 30°parking to 60° parking is hsin30°/hsin60° = .50.

 Susanta Sanyal said: (May 7, 2021) 0.8 is the correct Answer.
