Someone asked me this today.

If

4 + 6 = 60,
4 + 8 = 61,
7 + 8 = 62,
11 + 12 = ?

I'm unable to find the logic here. Can you guys solve this?

  • $\begingroup$ Btw, I am told that the answer is 61. $\endgroup$ – Rajan Feb 26 '18 at 10:34

    $\begingroup$ Nup that's wrong, Obviously the answer is 63. It's a simple sequence, independent of the LHS. $\endgroup$ – theonetruepath Feb 26 '18 at 10:37
  • $\begingroup$ I thought exactly the same. But the reasoning is different here I guess. $\endgroup$ – Rajan Feb 26 '18 at 10:40

I think answer is

61
Logic : The numbers on the left are months of the year and answer is total days in those months.

why not 72?
(4 + 6) * 6 + 0 = 60
(4 + 8) * 5 + 1 = 61
(7 + 8) * 4 + 2 = 62
(11 + 12) * 3 + 3 = 72

    $\begingroup$ Nice idea, but it doesn't explain why the numbers in the LHS are what they are. $\endgroup$ – Evargalo Feb 26 '18 at 14:58

4+6=60
4+8=61
+3
7+8=62
+4-+4
11+12= 23X3=69

Answer = 69

    $\begingroup$ Welcome to Puzzling.SE . Could you elaborate on your answer ? Right now I fail to grasp the logic behind those calculations... $\endgroup$ – Evargalo Feb 26 '18 at 14:57
