<PRE><B>Question 467030</B>
Speed in still water = x mph
speed of current = y mph
against current x-y		3.00	hours					
with current x+y		1.50	hours					
								
Distance = same=		12						
t=d/r								
12	/	(	x	-	y	)=	3.00	
3	(	x	-	y	)	=	12.00	
3	x		-3	y	=	12	....................1	
12	/	(	x	+	y	)=	1.50	
1.50	(	x	+	y	)	=	12	
1.50	x	+	1.50	y	=	12	...............2	
Multiply (1) by 1							
Multiply (2) by	2							
we get								
3	x	+	-3	y	=	12		
3	x	+	3	y	=	24		
6	x	=	36					
/	6							
x 	=	6	mph	Boat speed				
							
Let the number of bees be x
1/5 x Kadamba
1/3 x Silandhara

3(1/3 x -1/5 x )  arbor

1 bee no flower

x/5 +x/3 +3(x/3-x/5)+1 =x

x/5+x/3+x-3x/5  +1 =x

LCD = 15
multiply by 15
3x+5x+15x-9x+15=15x

-x+15=15
-x=-15
x=15 bees
