Sulfur dioxide and chlorine are not produced because CNG is composed of methane. The fact that it produces large amount of carbon dioxide is not helpful or advantageous by any means. Whether it is used in compressed form or not does not make it eco-friendly; but, yes, it produces no smoke SPM upon combustion. So correct answer is (B).

Aditya Dash from Apeejay School, Noida
Subject :NSO    Class : Class 5

Ans 1:

Sohan R Jolapuri from Amanora School, Pune
Class : Class 5
Answer: B Explanation: Arrange the Question mathematically to get the following:- (1617/ 7) X 6 because 1617/7's 6th multiple is written in this way - (1617/ 7) X 5 because 1617/7's 5th multiple is written in this way. Calculate this like this:- 1617 / 7 = 231. So, (1617/ 7) X 6 = 231 X 6 = 1386 And, (1617/ 7) X 5 = 231 X 5 = 1155. Thus, we can calculate, 1386-1155 = 231 Hence, option B, with 231 as the answer, is correct.
