A car is travelling at a uniform speed. The driver sees a
milestone showing a 2-digit number. After travelling for an
hour the driver sees another milestone with the same digits
in reverse order. After another hour the driver sees
another milestone containing the same two digits. What is
the average speed of the driver.

First milestone : 10x+y
Second milestone : 10y+x
Third milestone: 100x+y

Since the speed is uniform so
Distance covered in first Hr = Distance covered in Second Hr
(10y+x)-(10x+y) = (100x+y)-(10y+x)
After solving, we get ----> y=6x but since x and y are
digits so only possible combination is x=1 and y=6,
So average speed = 45 KM/HR

Rajesh is correct.
It mentiones clearly that the car is moving in a uniform
speed. hence we have to find a number ab (b - units place
and a - tens place, eg, in number 46, a = 4 and b = 6)such
that ba-ab = axb - ba. Only then the speed will be
uniform.. The only combination possible that way is 16,61
and 106. hence the average speed is 45 km/hr

First milestone : 10x+y
Second milestone : 10y+x
Third milestone: 100x+y

Since the speed is uniform so
Distance covered in first Hr = Distance covered in Second Hr
(10y+x)-(10x+y) = (100x+y)-(10y+x)
After solving, we get ----> y=6x but since x and y are
digits so only possible combination is x=1 and y=6,
So average speed = 45 KM/HR

the distance traveled between 1st mile stone and 2nd milestone is 61-16 = 45 and the distance traveled between 2nd and 3rd is 106-61 = 45 , so the average speed is 45 km/hr

Rajesh & Ram are wrong .. b'coz think of the driver is going
from kanniyakumari to kashmir let it be Kashmir 1000miles
after few miles the driver will see kashmir 800 miles

after few miles he cud see Kashmir 600miles

...................

So while travelling from one place to another the distance
will decrease .. it won't increase

what will come in place of the question mark(?)in the
following alphabet series?
AC DC EF IG?
1)MI 2)IL 3) IM 4)LI 5)None of These
plz ans hurry and with detail

A son and father goes for boating in river upstream . After
rowing for 1 mile son notices the hat of his father falling
in the river. After 5 min. he tells his father that his hat
has fallen. So they turn around and are able to pick the
hat at the point from where they began boating after 5 min.
Find out the speed of river.

Find (7x + 4y ) / (x-2y) if x/2y = 3/2 ?
(a) 6
(b) 8
(c) 7
(d) data insufficient
Can anyone help me out to get answer for this question,i
have exam on 6 th april can anyone find me the answer
before that and post it please!!!!!!!!

1. 2 containers labeled A and B are filled with red and blue
marbles in given quantities: -

Each container is shaken vigorously. After choosing 1 of the
container, without looking, draw out a marble. From which
container you have the max probability of choosing a blue
marble?
