In a class of 70 students, the ratio of boys and girls is 4:3. Among the girls the ratio of the number of rich and poor is 1:4. If the ratio of the number of rich and poor students is 8:27. Find the ratio of the number of rich and poor boys in the class.
A. 1:3
B. 1:4
C. 1:2
D. 2:3
E. 5:7

• total rich students =70*8/35=16
  total poor students=70*27/35=54
  no of rich girls=70*3/7*1/5=6
  no of poor girls=70*3/7*4/5=24
  so,no of rich boys is=16-6=10
  no of poor boys is=54-24=30
  final ratio is =10:30 i.e 1:3
