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

On a given day, a bank had 16000 cheques returned by
customers. Inspection of the first 800 cheques indicated
that 100 of those 800 had errors and were therefore the
available immediately for data processing. On this basis,
hwo many cheques would be available immediately for data
processing on that day?

Q.15 For the FIFA world cup, Paul the octopus has been
predicting the winner of each match with amazing success.
It is rumored that in a match between 2 teams A and B, Paul
picks A with the same probability as A’s chances of
winning. Let’s assume such rumors to be true and that in a
match between Ghana and Bolivia, Ghana the stronger team
has a probability of 2/3 of winning the game. What is the
probability that Paul will correctly pick the winner of the
Ghana-Bolivia game?
4/9
2/3
1/9
5/9
Answer is: 5/9
can someone plz explain how this ans is calculated?????
