Shailaja Tiwari
they must have done by this way :ianoopWhat is logic for getting 18?
- 9 = 90
- (8*9=72)
- 8 = 72
- ( 7*8=56)
- 7 = 56
- (6*7=42)
- 6 = 42
- (3*6=18)

Really this is logicπ¨ , where did 9=90 came fromβ and why 3 came in series after 6, while other numbers are just x-1.Shailaja Tiwarithey must have done by this way :
- 9 = 90
- (8*9=72)
- 8 = 72
- ( 7*8=56)
- 7 = 56
- (6*7=42)
- 6 = 42
- (3*6=18)
- 3 = ??
Why not x = x*(x+1). -
Shailaja Tiwari9=90 - as 8 is multiplied with its higher consecutive no. 9,similarly they must have added 9 with its higher consecutive no.10.
and don't know about the series problem ,others may not have noticed it -
Shailaja Tiwarianyway what's the right answer/
π¨ -
Ajay PandeyRight answer is 18 or 12 depends on ur logic.In objective exams, options must be either 12 or 18 not both.My answer is 12 bcos first match a pattern and then relation between consecutive options.

At first I thought you must have posted in the wrong thread. But now I think I see that you think the answer 18 is bad logic, a non sequitur, so you posted your own non sequitur to protest. Right?Aadit Kapoorwrite a program to print a message without using printf function.
BTW. The answer to your puzzle is trivial if using one of the many computer languages that don't have a printf function. -

Shashank MogheWell 18 (3-4 seconds). Also, if you (want to) intrapolate the series, the answer comes to 12. There seems to be a confusion as to which one is correct.
If it were up to me , I would justify 18 as the correct answer because of the way the question is presented. I was not "told to" intrapolate. -
