Read Solution (Total 4)
-
- Considering total no of males as x and total no of females
as y, we get first eqn as x+y=35000.
Now males are increased by 6% and females by 4%, so we get
2nd eqn as 1.06x+1.04y=36700.
Using simultaneous eqn, we get
No of males=15000
No of females=20000 - 10 years agoHelpfull: Yes(8) No(0)
- let males be x
let females be y
then initially, x+y=35000...........(1)
when increased,
x+(6x/100)+y+(4x/100)=36700............(2)
from (1) and (2),
(6x/100)+(4x/100)=1700
10x=170000
x=17000
and y= 18000 - 7 years agoHelpfull: Yes(2) No(0)
- 17650 males
17350 females - 9 years agoHelpfull: Yes(0) No(1)
- 18180 Female & Male 18520
- 9 years agoHelpfull: Yes(0) No(0)
