u can say the puzzle test.here are the questions
1. there is a number which is slightly
lesser than 500, which when divided by 3,4,5,7 leaves no remainder (3 marks)

2..In a party, there one man dances exactly
with 3 ladies & 1 woman dances exactly with 3 men . there are exactly two

them.
ans
edward is the youngest
4. One day Harry and I set our watches
together. None of us was aware that my watch was getting faster by 2 min per
hour and Harry’s watch was getting slower by 1 min per hour. After sometime, we
discovered that my watch was 1 hr ahead of Harry’s watch. Can you find out after
how long we noticed this ? (3 Marks)
Ans:
the differnce between the time would be 2min + 1min= 3min
so there is a diff of 3min for
every 1 hour
therefore diff of 60 min
would be 60*1hour/3min
there fore the answer is
20 hours
5. there is well of depth 30m and frog is
at bottom of the well. he jumps 3m in one day and falls back 2m in the same

9. THIS IS A TOUGH ONE BUT I MANAGED TO GET
THE ANSWER.
there are a number of cuffs and collar pieces
which belong to freddy and charlie. there total is 30. freddy and charlie give
all of tem to the laundry. freddy collects half the number of cuffs and one-third
the number of collars and pays his share of 27 cents. 4cuffs costs 5collars.now
tell how much did charlie pay for his share?
solution:: let the TOTAL number of the cuffs
be X
let the TOTAL number of the COLLARS BE be 30-X
NOW FREDDY COLLECTS 1/2*X + 1/3*(30-X) =
X/6 + 10
so charlie would collect 1/2*X + 2/3*(30-X) = -X/6 + 20
by inspection and trial and error we can
see that X=12 ((( there is no other
way)))
now putting X=12 in first equation we get
12 and puttin in eqn 2 we get 18
there fore freddy pays 27cents for 12 pieces
so charlie will pay ____ cents for his 18
pieces
THE ANSWER WILL BE 40.5 CENTS
10.
Y X
Z Y
I DON' REMEMBER THE FULL QN, BUT THE QN WAS TO FIND VALUES
X Z
OF X Y Z. THE ANSWER IS X=9
-----------------
Y=1
Y X X
X Z
Z=8
