you assumed that they together can copy 140 pages coz' 70 per head, which is wrong. its clearly mentioned 70 pages together. if you go by your way it would 140-50 = 90 which B can copy in 10 hrs. which is not right.Rather, 70-50 = 20, which B can copy in 10 hrs. so B would copy 26 pages in:(26/20)*10 = 13 hrs.

A = 50
A+B = 70
B = 70 -50 = 20
B = 20 For 10 Hours
20Pages = 10 hours
1 pages = 10/20 =1/2
26 pages =(26*1/2)
26 pages = 13 hoursSimeon

hi,
i think
it can be 15 bcoz
2x+3y+4z=15
3x+2y+z=10
adding
5x+5y+5z=25
x+y+z=5 that is for 1 orange ,1 bannana and 1 apple requires 5Rs.
so for 3 orange ,3 bannana and 3 apple requires 15Rs.
i.e. 3x+3y+3z=15........Ashok Rawat

Hi
I think
I can be 15 bcz
2x+3y+4z=15
3x+2y+1z=10
So adding

Let 5 LCM
5(x+y+z)=25
x+y+z=5
So 1 orange, 1 banana, 1 apple is cost 5 Rs.
Then 3 orange, 3 banana, 3 apple costs 15 Rs.
its solved. Ans= 15

11. After 10 years A will be twice the age of B before 10 years and now if the difference is 9 years between them then what is the age of B after 10 years.
Let present ages of A and B be x and y respectively.
According to the question
x+10 = 2(y-10) after solving we get
x-2y = -30 eq. (1)
x-y = 9 eq. (2) after solving above equation we will get there present ages as such A = 48 and B = 39.
After 10 years B will be 49 yrs

Let us take pure milk contains 100 litre
20% replaced by water =>100*20/100=20
100-20=80
now 80 litre milk is available
Again 20% replaced by water =>80*20/100=16
80-16=64
now 64 litre milk is available
Again 20% replaced by water =>64*20/100=12.8
64-12.8=51.2

First Race=x
Second Race= x+6
Total = Rs. 68
x+(x+6)=68
2x+6=68
2x=68-6
2x=62
x=62/2
x=31
First race=Rs. 31
Second race= 31+6= Rs. 37
4 more in second race= 37+4= Rs. 41 -

ans is green...
yellow box can have either of pink/yellow balls.
if we put a yellow ball in "yellow" box then it wud imply that "yellow" is also the colour of the box which has the red ball(becoz acordin 2 d question,d box of the red ball n the ball in the yellow box have same colour)
thus this possibility is ruled out...
therefore the ball in yellow box must be pink,hence the colour of box containin red ball is also pink....
=>the box colour left out is "green",,,which is alloted to the only box left,,,the one which has yellow ball..
