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
