let
Number husbands taller than wife = x
Number husbands heavier than wife = y
Number of husbands taller and heaview =z
As per given conditions
2/3*x=z=3/4*y
x=3/2 z
y=4/3 z
x+y-z+120=1000
(3/2 + 4/3 -1)z=880
z*11/6 =880
z=880*6/11
z=480 - 12 years agoHelpfull: Yes(16) No(6)
- why the condition x+y-z+120=1000
- 12 years agoHelpfull: Yes(1) No(2)
