complete the series: 9=4, 21=9, 24=10, 16=? find ? a.10 b.4 c.7 d.5

OpenStudy (anonymous):

9=4, 21=9, 22=9, 24=10, 16=?

OpenStudy (anonymous):

haha, this one is cute

OpenStudy (anonymous):

in exam i used mu logic like this ........16 lies between 9 and 21 and therefore the ? must be between 4 and 9.......i guess

OpenStudy (anonymous):

but i dont which one correct but i punched option no.c in the answer box....

OpenStudy (anonymous):

is this a practice test or a real test?

OpenStudy (anonymous):

model test

OpenStudy (anonymous):

and it doesnt give explanations?

OpenStudy (anonymous):

no...

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

OpenStudy (anonymous):

waiting for a week

OpenStudy (anonymous):

given just 2 hrs ago

OpenStudy (anonymous):

c is correct

OpenStudy (anonymous):

yea i think so...but do u have any logic??

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

so whats that?

OpenStudy (anonymous):

well, first you have 21=9 and 22=9. That should tell you to not think so much about the actual values of the numbers.

OpenStudy (anonymous):

so.

OpenStudy (anonymous):

so you are going to have to think outside the box on this one. i don't want to just give it away as that doesn't really help you improve your logical reasoning.

OpenStudy (anonymous):

hey...i got a logic...

OpenStudy (anonymous):

and answer is 7..................and the explanation is....like this....9(nine)=4 letter...21(twentyone)=9 letters,,etc,,,,,,and this 16(sixteen)=7

OpenStudy (anonymous):

yup

OpenStudy (anonymous):

yea
