hi suresh

ans is "97"! am o correct?
bye:)

Answer is 79...

Solution

The next number is formed by adding the previous number with the individual digit in the number...

eg:-
25=17+1+7
32=25+2+5
37=32+3+2 and so on

Final value is 71+1+7=79

hi

i got 97 since
result

25-17=8


32-25 =7 result is decreased by 1 compared to previous result

37-32=5 result is decreased by 2 compared to prev result



47-37=10 result is doubled compared to prev result


58-47=11 result is increased by1 compared to previous result


71-58 =13 result is increased by 2 compared to previous result


now the previous result should b doubled!

i.e 13*2=26


therefore 71+26=97


thats what i thought!

Good Shenoy its also a good approach...
It is possible for a problem to have multiple solution...
One more request please provide solution when u post a reply so others also can learn...

hi manoj


yes , iwill take care of it! :D
but I dont write solution only when i answer the puzzle first(or say before 3hrs or so)!the only reason y i dont give solution is that i want others to think!( i want others to read and they should equally enjoy the question) .

What i think(personal view) is that giving solutions in the very first post itself kills the anxiety of others!
I hop u r getting my point!There is no reason other than this!
bye
:)

Yeah shenoy u r correct.. i didnt thought about that...

79.........

79 is the correct answer....

shenoy thinking differently....I post this puzzle using manoj concept....
