A girl has as many brothers as sisters, but each brother has only half as many brothers as sisters. How many brothers and sistes are there in the family?
This can actually be solved using mathematical equations. It's mosre or less like word problem!
Let the number of girls be x Let the number of boys be y
A girl has as many brothers as sisters
So, x - 1 = y
each brother has only half as many brothers as sisters
So, y - 1 = x ÷ 2 we can rewrite this as 2(y - 1) = x

So, x - 1 = y
each brother has only half as many brothers as sisters
So, y - 1 = x ÷ 2 we can rewrite this as 2(y - 1) = x
Putting x = 2(y - 1) into x - 1 = y
2y - 2 - 1 = y
Collecting like terms
2y - y = 2 + 1
y = 3
Putting y = 3 into x - 1 = y
x - 1 = 3
x = 3 + 1 = 4
So, x = 4; y = 3
Answer: 4 sisters, 3 brothers

Tata Power whose core business is to generate, transmit and distribute electricity has made no money to investors in the last one decade. That is a big blunder considering it is one of the largest power generation companies in the country. One of the reasons is the company's huge debt levels which stood at ₹43,559 crore at the end of March 2021 compared to the company’s market capitalisation of ₹44,447 crore.
