Question

If 23+21=61 82+36=12 90+41=63 Then 78+25=? Option A) 45 B) 87 C) 49 D) 31

Answer 1

/* Given options are wrong */

$Given \: 23 + \boxed {21}= 61 , 82 + \boxed{36} = 12 ,$

$90+\boxed {41 }= 63 , \: then \: 78 + \boxed{25} = ?$

/* Observe the sequence ,we can following pattern */

$\orange { The \:number \: in \: a \:box \:are}$

$\orange { interchanged \:their \: position\:and}$

$\orange { placed \: in \:next \: sequence \: result}$

$a ) 23 + \pink{2}\blue{1} = 61$

$b ) 82 + \pink{3}\blue{6} = \blue{1}\pink{2}$

$c ) 90 + \pink{4}\blue{1} = \blue{6}\pink{3}$

$s ) 78 + \pink{2}\blue{5} = \blue{1}\pink{4}$

Therefore.,

$\red{78+ 25}\green { = 14}$
