This is a simple yet tricky puzzle. It seems this puzzle has been solved by pre schoolers in an average 10 Mins. By entry level programmers in around 30 Mins. And strangely people good in mathematics have taken more time to solve this riddle. Check which category you belong to. If you get the answer simply post the value in comment section. Within a day or two I will post the explanation.

ReplyDeleteexplanation bhi de do plz... mein to ye soch ke khush ho gaya ki 1 ghanta se jyaada ho gaya aur mein solve nahi kar paya tha i.e I am good in Maths :P
ReplyDeleteAs I said not much of Maths logic. Just count the number of circles or close loops. For example in 8 there are two loops, in 6/9 there is one loop and in 1,3 etc there isn't any. So the number of loops in 2683 is 1(for6)+ 2(for(8)=3.
ReplyDeleteHope you enjoyed solving it..
