Answer: 1 Mark

Given that
Anubha's father weighs 91 kg.
Anubha's dog's weight=$\frac{1}{7}$ of Anubha's father's weight

$\Rightarrow \frac{1}{7}\times 91$

$\Rightarrow \frac{91}{7}\Rightarrow 13kg$


Also given
Anubha's mother's weight= 5 times Anubha's dog's weight

$=5\times 13=65kg$

$\therefore$ Anubha's mother weighs 65 kg.
