7.

An aggregate which passes through 25 mm I.S. sieve and is retained on 20 mm sieve, is said to be flaky if its least dimension is less than

 [A]. 22.5 mm [B]. 18.5 mm [C]. 16.5 mm [D]. 15.5 mm [E]. 13.5 mm.

Explanation:

No answer description available for this question.

 Itaf Hussain said: (May 20, 2014) (25+20)/2 = 22.5. Now 3/5 of 22.5 i.e 13.5.

 Ankit Katiyar said: (Dec 31, 2015) If you want to find elongation index 9/5 of 22.5.

 Shadab said: (Nov 13, 2016) 60% of avg. 0.6 * (25 + 20/2) = 13.5.

 Rita said: (Nov 9, 2017) 20+25/2 = 22.5. 22.5*3/5 = 13.5.

 Umesh Kumar said: (Jun 23, 2019) (20+25)/2 = 22.5. Flaky aggregate of dimensions = 22.5*3/5 = 13.5.

 Omkar said: (Feb 3, 2021) 0.6 time of Avg dimension. 0.6 * (25+20/2) = 13.5.

 Waqar Khaliq said: (May 24, 2021) 20+25 = 45. 45/2 = 22.5. As know agg are flaky when least dimension is 3/5. So, 22.5*3/5 = 13.5.
