brother and sister
3:4
3x:4x
3x+4x=420
7x=420
x=60
smaller number=3(60)=180.
the answer is 3:10
explanation:
let the first number be x
and the second number be y
(7/8)((3/7)x)=(25/100)((45/100)y) given
ie.., 21x/56= 9y/80
on solving we get x:y= 3:10
is the answer
yea may be they are brothers only by father or by mother

8+1=9
9+2=11
11+3=14
14+4=18
18+5=23
and finally
23+6=29
16 poles per min
48kmph=48000 meters per hr
=800 meters per min
800/50=16 poles per min
No sentence can end with because because, because is a conjunction
I would design a voice integrated clock that reads out the time aloud whenever people ask for time
Let the revolutins made by bigger wheel is: x
then revolution by smaller wheel will be: x+10
Now, the distance covered by both wheels will be same.
So,
7(x+10)=9x
7x+70=9x
70=2x
35=x
so distance travelled=9*35=315
or 7*45=315
