In a family there are some boys and girls. All boys told that they are having equal no of brothers and sisters and girls told that they are having twice the no. of brothers than sisters. How many boys and girls present in a family?

• in family there r 4boye n 3 girls are there.
  lets explain
  boys except themselves has three brothers n three sisters means that is equal..bcoz when we count brothers we dont count our selves.
  
  in casee of girls every girl has 2 sisters n four brothers ,so each girl has twice no of brothers than sisters.....

• let there r b boys and g no of gals
  so,when the boy is counting,then b-1=g
  when the gal is counting,then b=2(g-1)
  so,solving above 2 eqn,we get g=3 and b=4..

• Suppose b be d no of boys n g no of girls
  when boys told dey r nt including demselves so
  b-1=g
  similarly for girls
  2(g-1)=b
  Solving both eqns we get
  no of girls=3 n no of boys=4

• Total number of boys = 4
  Total number of girls = 3
  Each boy will have 3 brothers and 3 sisters (equal in number)
  Each girl will have 2 sisters and 4 brothers (brothers = 2* sisters)

• no. of boys be B and girls be G.so acccording to given problem B-1=G and 2(G-1)=B.So 2G-3=G on solving G=3 and B=4
