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.
