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: -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 Q10
What is the maximum number of times a single page of a newspaper can be folded in half by hand?
The question asked how many times it can be folded into half, not quarters, not 10 times. You can only fold a paper into half once, if you fold it again it's now quarter.
Answer: Once
