IQ Test Answers
The answers to IQ test questions asked
above are given below.
1. 10 miles each according to Pythagoras Theorem.
2. Each Cow has 2 eyes and 4 legs and each
bird has 2 eyes and 2 legs. Lets call each eye as x and each leg as y. Also
each bird is n and each cow is m so:
n(2x+2y) + m(2x + 4y) = 172x + 344y
2x (n+m) + 2y(n+2m) = 172x + 344y
(n+m) = 86 and (n+2m) = 172
n = 86 - m
86 - m + 2m = 172 or m = 86
This implies n = 0.
So, the owner has 0 birds and 86 cows.
3. This is a classic probability puzzle and
many puzzles are based on this logic. If the person picks up two socks then
there is a possibility of them being different in colour. If he picks up three
socks then they are guaranteed red or white. So the minimum number of socks
required are three.
4. Let the number be x
105 - x = y
x = 105 - y
13x = 105 + y
14 x = 210
x = 15
x = 105 - y
13x = 105 + y
14 x = 210
x = 15
5. 10 minutes. The total time was one hour
and already 50 minutes are over.
6. You can assume that when the fly lands on cyclist 1 they are 50
miles apart. The fly has to travel 50 + x miles at 16 miles/hour. Here x is the
additional distance at 10 miles/hour. So the problem is now simplified as
y = 50 + x (distance)
(50 + x)/16 = x/10 (time)
500 + 10x = 16x
6x = 500
x = 250/3 = 83.33
y = 133.33
7. Daughter
8. When they meet they are both at the same
distance away from London.
9. 10 km. Because the dog's speed is 10 km/h.
10. First, work out how much of the pool gets
filled by each tap in one hour. The first tap takes 48 hours to fill the pool,
so in one hour it fills 1/48 of the pool. The second tap 1/72. The third tap
1/96. And the fourth tap fills
1/6 of the pool in one hour. We need to add
all those fractions together:
1/48 + 1/72 + 1/96 + 1/6 = 61/288
So, in one hour the pool
will be 61/288 full and it will be completely full in 288/61 hours = 4 hours 43
minutes and 17 seconds.
11. Tommy was the thief. He was not telling
the truth. He stole it.
12. If the guy was from the west, he should answer the truth: I am
from the west. If the guy was from the east, he also should tell a lie: I am
from the west. The answer will always be: 'I am from the west'. So we know the
tour guide was telling the truth.
13. If the horse is brown. then every one is
right. This is not the answer. If the horse is black, then every one is wrong.
This is not the answer either. Therefore, the horse is gray. To verify the
answer, Allan was right, Brian was right, but Charlie was wrong.
14. Since there is no conflict between what
they said, it meant that either they both told a lie or both told the truth. In
this case they both told a lie. The answer is the brother is older.
15. The number will be 41312432 or 23421314.
Of course these 2 numbers are actually the same, just reverse the direction
from one to become another one. The way to solve this is, first all, put down
two 4s and reserve 4 spaces between these two 4s. Then you determonw the positions
for two 3s. Since you can not put both 3s between 4s, one 3 must be outside of
two 4s. After that you just need to try a few cases to find out he answer.
16. (a) 8 Minutes because each monkey takes 8
minutes to eat a banana. (b) 8 Monkeys are required to eat
48 bananas in 48 minutes. Each money will eat
6 bananas.
If you feel that above questions are too easy then the below puzzle is for u try to crack it.
if u did it then definitely u are one of the few in the world
Three gods A , B , and C are called, in some order, True, False, and Random. True always speaks truly, False always speaks falsely, but whether Random speaks truly or falsely is a completely random matter. Your task is to determine the identities of A , B , and C by asking three yes-no questions; each question must be put to exactly one god. The gods understand English, but will answer in their own language, in which the words for yes and no are “da” and “ja”, in some order. You do not know which word means which.
the following clarifications are provided for the above question
- It could be that some god gets asked more than one question (and hence that some god is not asked any question at all).
- What the second question is, and to which god it is put, may depend on the answer to the first question. (And of course similarly for the third question.)
- Whether Random speaks truly or not should be thought of as depending on the flip of a coin hidden in his brain: if the coin comes down heads, he speaks truly; if tails, falsely.
ALL THE BEST
