Caterpillar Placement Paper

1.Two trains are
travelling between two stations at a constant speed of 25kmph.The
stations are 50km apart .A bird traveling at 100kmph starts its
flight along with one train and travels in the same direction until
it meets the other train. It changes its direction and goes in the
reverse direction until it meets the initial train. Find the distance
travelled by the bird before the two trains collide.

2.A flight carrying food
packets is flying at a height of 1960m from the ground. The speed of
the flight is given. Find the time taken for a food packet dropped at
that instance to hit the ground.

(Hint: Use
s=ut+(at^2)/2.Initial velocity as 0 coz the dropped food packet does
not have velocity in the vertical direction.) when a square is
constructed on 3 sides of a triangle ,their sides are in the ratio
1:3:4,THE WAT triangle is it x2+y2=45,xy=18,then 1/x+1/y=
x-11/x>13/15,then x=

3. in race 100m,b bet c
by 25m.a bet b by 20m.then a will beat c by what metres

4. 5 tables and 10 chairs
were sold for 20000.15%gain for table,10%loss on chair. Overall
profit rs 750.the cp of table is?

5. a man rows in still
water in 9kmph in 2hr.if upstream vel is 2times down, then find speed
of stream

6. h:base dia of a cone
is 3:2.icecream is filled using hemisphere scoop whose half part is
inside cone. if total length of ice-cream is 36 cm, find vol of
ice-cream

7. a,b,c complete work in
4 days.a &b finish in 7 days.time for c is & similar sums
length of line perpendicular to given line

8. eqn avg of 5 players
is x. addition of 6th player increases avg by 2.add od 7thplyr
decreases avg by 2.runs of 7th player is

9. if 500 more cows r
there then each cow gets 40% less hay.the no of cows is value of gold
is increasing by 11%.if present value is 10000,then value before 2
months is?

10. venn diagram verbal
sum an amount doubles in 5 yrs due to SI.wat will be the value of the
amt.in 13yrs 9 months if principal is added every year first a=I vaue
of a square is assigner to b c=b+1 if squareroot of c>5o
terminate,else go to beginning what is the last value of c
