Answer to Q2
This is actually a trick question. If you pay attention to the question, you will see it asked how many apples you have not how many apples are remaining!
So the correct answer is 6! Because both 4 apples you took and the remaining 2 in the bowl are all yours.

Answer to Q3
Divide 40 by half and add 15!
Divide 40 by ½
40 ÷ ½ = 40 x 2 = 80
Add 15 to 80
80 + 15 = 95
Answer: 95

Answer to Q4
What is the solution for 6÷2(1+2)?
Remember BODMAS - Bracket Order Division Multiplication Addition Subtraction
So we do Brackets first (1+2) = (3)
6÷2(3) but we can rewrite that as 6÷2x3
So we do our division next: 6÷2 = 3
3x3 = 9
Answer: 9

Answer to Q5
If you choose an answer to this question randomly, what's the probability you will be correct?
Since 4 options were given, the probability of you choosing a correct answer will be 1 (the number of answer you can choose at a time) divided by 4 (total number of answers you can choose from) multipled by 100%
Answer: (1÷4)x100% = 25%

Answer to Q6
If 32° Fahrenheit equals 0° Celsius and 212° Fahrenheit equals 100° Celsius. At what temperature will Fahrenheit and Celsius be the same?
If,
32°F = 0°C [eqn i]
212°F = 100°C [eqn ii]
When will x°F = x°C [eqn iii]
From eqns i, ii, and iii above, we can say
(212 - 32) ÷ (212 - x) = (100 - 0) ÷ (100 - x)
180 ÷ (212 - x) = 100 ÷ (100 - x) [eqn iv]
Cross multiplying eqn iv
100(212 - x) = 180(100 - x)
21,200 - 100x = 18,000 - 180x [eqn v]
Collecting like terms of eqn v
-100x + 180x = 18,000 - 21,200
80x = -3,200 [eqn vi]
Dividing eqn vi through by 80
x = -3,200 ÷ 80 = -40
Answer: -40

Answer to Q8
If a number is x, can x - x = x ÷ x?
Substracting a number from itself will always gives zero (x - x = 0), dividing a number by itself will always give one (x ÷ x = 1), so that equation can never be true!
Answer: No

Answer to Q9
On average, rabbits start breeding when they are 3 months old and produce 4 offsprings every month.
If I put a day old rabbit in a cage for a year, how many offsprings will it produce?
Many will rush to calculate (12 months - 3 months) x 4 offsprings = 36 offspings but note the question says putting just one rabbit inside a cage, it takes a male and female rabbit to make a baby!
Answer: 0 (only one rabbit can't make babies)

Answer to Q12
Figure out the correct code
6 | 8 | 2 - One number correct and placed well
6 | 1 | 4 - One number correct but placed wrongly
2 | 0 | 6 - Two numbers are correct but placed wrongly
7 | 3 | 8 - Nothing correct
8 | 7 | 0 - One number correct but placed wrongly
First clue says 6 | 8 | 2 - One number correct and placed well so we know the correct code will be like one of these 6 _ _, _ 8 _ or _ _ 2
Second clue says 6 | 1 | 4 - One number correct but placed wrongly so we know our code might contain one of 6, 1, or 4 and it won't be at their current positions
Third clue says 2 | 0 | 6 - Two numbers are correct but placed wrongly so we know either 2|0, 0|6 or 2|6 is correct but not in their current positions
Fourth clue says 7 | 3 | 8 - Nothing correct so we know our code can never be _ 8 _ (so we are left with 6 _ _ or _ _ 2)
Fifth clue says 8 | 7 | 0 - One number correct but placed wrongly but from fourth clue we can't have 7 and 8 as part of our code so we know 0 is part of our code
Now we know 0 is part of our code and if we go back to the third clue we now know 0 is one if the two correct numbers and the 0 can't be in the middle position and from fifth clue it can't also be in the last position of our final code so our code is definitely in the format 0 _ _
Going back to first clue we now know 6 _ _ (since that is starting with 6 and not 0) and _ 8 _ (earlier proved) can't be correct so our correct format is _ _ 2 (i.e. 0 _ 2)
Going back to second clue, we now know 6 is out and we are left with either 1 or 4 and since we are now looking for the middle number, we know it can't be 1 so it's definitely 4
Answer: 0|4|2

Going back to second clue, we now know 6 is out and we are left with either 1 or 4 and since we are now looking for the middle number, we know it can't be 1 so it's definitely 4

Answer to Q13
If,
A + A = B
B + B = D
A + D = E
What then is B + D + E
Numbers are been replaced with alphabets here: A = 1, B = 2, etc
1 + 1 = 2 (A + A = B)
So, B + D + E = 2 + 4 + 5 = 11. K is 11th on the list!

Answer to Q14
2 + 2 × 🐧 + 2 - 2 - 2 = 0
What is 🐧?
Remember BODMAS - Bracket, Order, Division, Multiplication, Addition, Substraction
So, 2 × 🐧 = 2🐧
We now have 2 + 2🐧 + 2 - 2 - 2 = 0
Collecting like terms 2🐧 = 2 + 2 - 2 - 2
2🐧 = 0
So, 🐧 = 0 ÷ 2 = 0
Answer: 0
2 + 2 × 🐧 + 2 - 2 - 2 = 0
What is 🐧?
Remember BODMAS - Bracket, Order, Division, Multiplication, Addition, Substraction
So, 2 × 🐧 = 2🐧
We now have 2 + 2🐧 + 2 - 2 - 2 = 0
Collecting like terms 2🐧 = 2 + 2 - 2 - 2
2🐧 = 0
So, 🐧 = 0 ÷ 2 = 0

Answer to Q15
How many seconds are in a year?
What first comes to mind here is that the question is asking for the number of seconds in time in a years, so let's calculate that!
365 days x 24 hours x 60 minutes x 60 seconds = 31,536,000 seconds
That is not in the options so the 21,920,000 was placed there as a bait.
What could the question be asking then? The second of every month i.e. 2nd of January, 2nd of February, etc...
Answer: 12

Answer to Q18
If 1 + 4 = 5; 2 + 5 = 12 and 3 + 6 = 21
What is 5 + 8 = ?
This is a sequence that follows the pattern x + (x*y), let's check!
1 + 4 = 1+(1x4) = 1 + 4 = 5
2 + 5 = 2+(2x5) = 2 + 10 = 12
3 + 6 = 3+(3x6) = 3 + 18 = 21
So we are right!
5 + 8 = 5+(5x8) = 5 + 40 = 45
