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.
