Answer 1

$\large\mathsf{Hoy !!}$
$<i>$
Let,

Girl = x

Black boy = y

Mummy = z

$\large\mathsf{\underline{1st \ pic}}$ :

( x ) × ( x ) = 16

x² = 16

x = √ 16

x = √ ( 4 × 4 )

x = 4

$\large\mathsf{\underline{2nd \ pic}}$ :

( x ) × ( y ) × ( y ) = 36

4 × y² = 36

y² = 9

y = √ 9

y = 3

$\large\mathsf{\underline{3rd \ pic}}$ :

( x ) × ( y ) × ( z ) = 72

4 × 3 × z = 72

12 × z = 72

z = 6

$\large\mathsf{\underline{4th \ pic}}$ :

( x ) + ( y ) + ( z )

= 4 + 3 + 6

= 13

Hence,

Option C. 13 is correct.
