WIPRO APTITUDE PAPER
WIPRO APTITUDE PAPER
1) In most states in India the law for the
sale of alcoholic beverages provides that beer cannot be sold after a certain
hour. However, in some States the law permits a customer to consume, after the
deadline, what has been sold before the curfew. In a certain bar 2 men ordered
sufficient beer to cover their probable requirements in anticipation of the
curfew. One man ordered and paid for 5 bottles and the other man ordered and paid
for 3 bottles. But as the curfew started, an old friend of both the men
approached and requested them to share the eight bottles of beer between them.
The friend thanked the two men and put down Rs 8 in payment for the beer he had
consumed, asking them to share the money in proportion to the quantity of beer
they have contributed to him. How should this money be equitably divided
between the two men?
a. Rs 7
and Rs 1
b. Rs 6
and Rs 2
c. Rs 5
and Rs 3
d. Rs 4
and Rs 3
Correct
Option a
Explanation:
The
three men shared the beer equally and so each drank the contents of 2(2/3)
bottles. Therefore the man who had brought 5 bottles contributed 2(1/3) and the man who had paid for 3 bottles
contributed 1/3 of the bottles, to make the third man’s share.
The
first man’s contribution is 7 times that of the second and therefore he gets Rs
7 and the latter Rs 1.
2) Two
trains start from two opposite directions towards each other. The stations from
which they start are 50 miles apart. Both the trains start at the same time on
a single track. A falcon which is sitting on one train, starts at the same time
towards the other train , as soon as it reaches the second one, it flies back
to the first train and so on and so forth. It continues to do so, flying
backwards and forwards from one train to the other until the trains meet. Both
the trains travel at a speed of 25 miles per hour, and the bird flies at 100
miles per hour. How many miles will the falcon have flown before the trains
meet?
a. 75
miles
b. 100
miles
c. 150
miles
d. 200
miles
Correct
option b
Explanation:
At 25
miles/ hr both trains will take 1 hr to meet or cover the distance of 50
miles.In 1 hr the falcon can travel 100 miles.
3) An unscrupulous
trader decided to make some extra profit on coffee
He bought one type
of coffee powder at Rs. 32 a kilo and mixed some of it with a better quality of
Coffee powder
bought at Rs. 40 a kilo, and he sold the blend at Rs. 43 a kilo.
That gave him a
profit of 25 per cent on the cost.
How many kilos of
each kind must he use to make a blend of a hundred kilos weight?
4) When a number
is multiplied by 13, it becomes greater to 105 by an amount with which it is
lesser to 105 by now. What is the number?
5) Four Friends in
the sixth grade were sharing a pizza. They decided that the oldest friend would get the extra piece. Randy is two
months older than Greg, who is three months younger than Ned. Kent is one month
older than Greg. Who should get the extra piece of pizza?
6) A box is filled
with 71 candies of the following flavours: lemon, raspberry, orange and grape.
There are twice as many lemon as raspberry candies. The orange-flavoured candy
count is one less than the raspberry candy count and there are six less grape
candies than lemon candies. How many candies do you have to take from the box
to have atleast two of one flavour?
7) A
standard-sized cigarette can be rolled out of 6 standard-sized cigarette butts.
How many cigarettes can be made
and smoked from 36 butts?
8) A student reached his school late by 20 minutes by
travelling at the speed of 9 kmph. Had he travelled at the speed of 12 kmph, he
would have reached hi school 20 minutes early. Find the distance between his
house and the school.
9) You are given two ropes and a lighter. This is the only
equipment you can use. If you light one end of the rope, it will take exactly
one hour to burn all the way to the other end. But it doesn’t have to burn at a
uniform rate. The second rope will also take an hour to burn from one end to
the other, but may do it at some varying rate. Now you are asked to measure a
period of 45 minutes. How will you do it?
10) Four friends (Alfred, Becky, Charlie, and David) wish to
cross the old bridge over the river. However it is dark and the bridge is not
very safe. They decide that no more than two of them may cross at a time and
that the people crossing should carry a torch with them. Alfred is rather
nimble on his feet and can cross the bridge in only one minute. Becky is a bit
slower and takes two minutes. Charlie is a little overweight, so takes four
minutes. David is the slowest due to a sprained ankle. He takes eight minutes.
They only have one torch between them, so when crossing in a pair, they must
stick together, thus crossing at the speed of the slower person. Devise a
scheme for the four friends (and their torch) to cross the river in as short a
time as possible.
