[quote]the answer for the puzzle is

2+5+3=132
3+6+4=380
4+2+7=63
6+3+6=228
8+5+2=?
rule is
a+b+c = p*q where p=(a*b)+1 and q=(b*c)-c
following the above we have
for 8+5+2, p=(8*5)+1=41 and q=(5*2)-2=8 ; p*q=41*8=328

8+5+2=328[/quote]


That was really typical to solve, I could never get it. Please try to post some easy ones, so that it could be answerable.

The answer to your this puzzle:
if 1=5
2=10
3=15

Answer: If 1=5 then 5=1...

Am I right Sajeetharan?? Do tell me...

Aastha Gupta
before answering how can 1=5..... :P :laugh:
Yes astha you are right!

@ rajani

it is a sequence and logic. so even 0 can be equal to 5
INFOSYS QUESTION
2 + 3 = 8
3 + 7 = 27
4 + 5 = 32
5 + 8 = 60
6 + 7 = 72
7 + 8 = ??
Let me try it..

2*1 + 3*2 = 8
3*2 + 7*3 = 27
4*3 + 5*4 = 32
5*4 + 8*5 = 60
6*5 + 7*6 = 72
7*6 + 8*7 = 98


Is the answer correct???

Aastha Gupta
yes aastha, great.

you have come up with a right answer.
Thanks Sajeetharan..

After all it was the INFOSYS question...Since I am Infy placed...

So I had to come up with the answer so I did...

Next number in the sequence


15, 161, 1771, 19481, 214291 is

Options:


1) 1942651
2) 135611101
3) 2424561
4) 1357101
5) 345372101
6) 1357201
7) 23651121
8) 1764924
9) 125461
10) 234255
15
161 : 1 (1+5) 1
1771 : 1 (1+6) (6+1) 1
19481 : 1 (1+7+1) (7+7) (7+1) 1
214291 : 1+1 (1+9+1) (9+4+1) (4+8) (8+1) 1
The first term is "2" because of the carry over from (1+9+1)
1357201 : 1 (2+1) (1+4) (4+2+1) (2+9+1) (9+1)1

So the correct option is option 6...
