Question

Vasant says, " I have as many sisters as brothers."

Vaishali says, "Each of us sisters has only half as many sisters as brothers. "
Assuming that Vasant and Vaishali are brother and sister, how many brothers and sisters are there in the family ?

• A. $8$ brothers and $6$ sisters
• B. $6$ brothers and $5$ sisters
• C. $5$ brothers and $4$ sisters
• D. $4$ brothers and $3$ sisters

Answer 1

The correct option is D $4$ brothers and $3$ sisters

Let no. of brothers be $x$ and no. of sisters be $y$.

As Vasant says:

$x-1=y$

as Vaishali says:

$x/2=y-1$

Solving both equations,

we get $x=4$ and $y=3$

So, there are $4$ brothers and $3$ sisters in the family.

option $D$.
