15+16=???
manitkapoor2:
add first digit of numbers
11+12=(1+2)(1+1)=32 not mathematical
12+13=(2+3)(1+1)=52
13+14=(3+4)(1+1)=72
15+16=(5+6)(1+1)=112
112 is the answer

actually there are two logics for this question 11 +12 = 23 where the last digit came to first and the first came to the last. and this logic replies everywhere.that's why 15 +16 = 31 which in inverse gets to be 13. and the second logic is the difference of 20 no.s.
so to ur question there are 2 answers and that are 13 by the fist logic and 112 by the other logic.
Hope this helps u !!

The answer is 13.
Given:
11+12 =32
12+13=52
13+14=72
To find:
15+16=???
Solution:
If we add 11 and 12, we get 23 as our answer, so it can be seen that in the given statement, the digits are reversed of the answer.
Similarly 12 + 13 = 25 but we have written it as 52 because the digits are reversed.
If we see 13+14 = 27, but after reversing digits it is 72.
So, it can be seen that elements on let side are added and then their digits are reversed to write the answer
15 +16 = 31
When we reverse the digits, answer will be 13.
Hence, 15+ 16 = 13
