If your answer is 13 then you are
right.
See the pattern of this question.
We have been given two sides:
Left Hand Side = Right Hand Side
But values on both sides are
different hence it is a logical puzzle.
First Equation:
16 = 62
Now if you look at L.H.S. which
is equal to 16
Reverse order of L.H.S. = 61
Add 1 = 62
Hence 62 is equal to R.H.S.
Now using the same pattern in
Equation 2 & see whether our pattern is correct or wrong:
55 = 56
L.H.S. = 55
Reverse order of L.H.S. = 55
Add 1 = 56
Hence it is equal to R.H.S.
Now again checking our pattern in
third equation:
28 = 83
L.H.S. = 28
Reverse order = 82
Add 1 = 83
It is equal to R.H.S.
Now solving final equation:
21 = ?
L.H.S. = 21
Reverse order = 12
Add 1 = 13
Hence it is equal to R.H.S.
So
Answer:
21 = 13
