Answer for question 5: The answer is 4. Multiply the upper left and lower right numbers together, then divide that by the bottom left number will give you your answer, e.g. (3×8)÷6=4. The same pattern applies to the other numbers.

Answer for question 6: It’s the top number minus the left and then multiplied by the right e.g (6-2x2 = 8) so the missing number is 3.

Answer for question 7: A post office.

Answer for question 8: The first line has three apples and = 30. You can assume each apple is worth 10.

The second line has one apple and two bunches of bananas and = 18. Because you know apples are worth ten then you assume each banana must be worth 4.

On the last line there are a bunch of bananas minus a coconut which = two. Because you know a bunch of bananas equals four a coconut must be two, right?

So your answer is probably 16 for the last line. Did you get that? Well, sadly that's wrong.

The actual answer is 14. Because you see, the maths sums are actually equal to the portion size of each piece of fruit. Get it? If two batches of four bananas are worth eight, it means each single banana is equal to one. And if a coconut is worth two, half a coconut must be worth one. This means, half a coconut (one) + apple (10) + three bananas (three) is equal to 14.

Answer for question 9: Peacocks don't lay eggs. It's actually a trick question.

Answer for question 10: 18. Someone has made a diagram explaining it here...
