Can anyone post ans to question12 (b) part. It looks quite simple but i think it's technically wrong question.

[QUOTE=Noreturn;956876]Can anyone post ans to question12 (b) part. It looks quite simple but i think it's technically wrong question.[/QUOTE]

It's a simple question and there is no need to complicate it in your own head. The information is literally given and all you have to do is write 2 lines down D:

i) Ahmed went to V or Z by bus. Cannot be deciphered which, given the lack of information

ii) Ali went to X by air

It can be thought of as a trick question, given how easy it was and the heavy marks it held.

Part (i) cannot be deciphered with the given information.

[QUOTE=Nazish Hina;913455]The universe has a total distance of 17.7 billion light years. Some star is 17.3 billion light years away. If it is eliminated/extinguished today, when will we see it?

If 3P+q=14 and P+2Q=12
What is P?

*I'm not sure about the values :D[/QUOTE]

Theses values are valid
3P+q=14
P+2Q=12

=> P= (14 - q) /3 ______eq I
=> P= 12 - 2Q_________eq II
By subtracting, we get
3P+q=14
P+2Q=12
-----------------
2p+q-2Q = 2
Divinding by 2,we get

=>P+q/2-Q=1

=>P=Q-q/2
=>Q=P+q/2
=>q=2(Q-P)

Any aforementioned value can be find out by putting these in above equation I and II.

it can deciphered without any doubt if you apply the rules of chronology.

The three boys, ali, akbar and nasir along with the mode of transport and destinations are in chronological order. Shahbaz who should have been placed on number two has been placed at number 5 just to ditch the candidates. If we place shahbaz on number two, everything will become clear.
thus Ahmad went to v by bus.
let me place all in chronological order
a. Ahmed went to v by bus
b. Shahbaz went to w by train
c. Ali went to x by air
d. Akbar went to y by car
e. Nasir went to z by boat

Complete Solution of 11(b)
 

Data:
1. Ahmad weighs thrice as much as Ali
[B][I]Ahmed=3(Ali)[/I][/B]

2. Ali weighs five times as much as Akbar
[B][I]Ali=5(Akbar)[/I][/B]

3. Akbar weighs half as much as Nasir
[B][I]Akbar=1/2(Nasir)[/I][/B]

4. Nasir weighs half as much as Shehbaz
[B][I]Nasir=1/2(Shahbaz)[/I][/B]

Solution:

Ahmed=3(Ali)
Ali=5(Akbar)
Akbar=1/2(Nasir)
Nasir=1/2(Shahbaz)

Let
Ahmed=a
Ali=b
Akbar=c
Nasir=d
Shahbaz=e

So,
a = 3b
b = 5c
c = 1/2(d) = 0.5d
d = 1/2(e) = 0.5e

Or,
a=3b
b=5c
d=2c
e=2d

As,
a=3b
and
b=5c

So,
a=3(b)=3(5c)=15c
a=15c

Similarly,
e=2d
and
d=2c

So,
e=2(d)=2(2c)=4c
e=4c

Now,
a=15c
b=5c
d=2c
e=4c

Arranging in descending order

a=15c
b=5c
e=4c
d=2c
c=c

In other words
Ahmed = 15(Akbar)
Ali = 5(Akbar)
Shahbaz = 4(Akbar)
Nasir = 2(Akbar)
Akbar = Akbar

So,
[B][I]i. Who is the heaviest in weight?[/I][/B]
Ahmed

[B][I]ii. Who is the lightest in weight?[/I][/B]
Akbar

[B][I]iii. Shahbez is lighter in weight than which of the two students?[/I][/B]
Ahmed and Ali

[B][I]iv. Shahbez is heavier in weight than which of the two students?[/I][/B]
Nasir and Akbar

[B][I]v. Show the descending order of weights of the two students?[/I][/B]
1. Ahmed
2. Ali
3. Shahbaz
4. Nasir
5. Akbar
