    If You Take 3 Apples From 10 Apples Riddle

    Hint:
    Three.

    If you take 3 apples from 10 apples, you are simply left with 3 apples.

    Many people confuse themselves with the mathematical equation, subtracting three apples away from 10 and therefore equaling an answer of seven apples. This is incorrect.

    You did not have any apples to begin with. So by taking 3 apples from 10 apples, you therefore now have 3 apples.

    A Man Steals 1000 From A Shop Riddle

    Hint:
    We can easily solve this mathematical problem by using the following mathematical process.

    Initial loss amount = Rs. 1000

    Now, we have to calculate the recovered amount,

    As the man spends Rs. 700 in the shop, the shop owner will surely provide the man goods/services of Rs. 700. So, nothing will be recovered in this case.

    Now, the man gave Rs. 1000 against the goods/services of Rs. 700 and got Rs. 300 change, so there will be no recovering of money for the shopkeeper.

    Final loss = Initial loss - Recovered amount = 1000-0 = Rs. 1000
    Did you answer this riddle correctly?
    YES  NO  

    7 Men Have 7 Wives Riddle

    Hint:
    If 7 men have 7 wives that simply means there are 7 coupled, so that is 7 +7 = 14.
    Then, if each couple has a child, that's 14 + 7 = 21.
    So the total number of people is 21.

    What Remains When The Roads Are Gone Riddle

    Hint:
    Let's take a look at the explanation of the riddle.

    As per the total laps in the race are 50 and the driver has completed 12 1/2 laps. This means, we have to subtract 12 1/2 from the total 50 laps. This equal to 37 1/2 or 37.5

    50 - 12 1/2 = 37 1/2 or 37.5

    Now, we need to calculate the fractional part of the race remains. For this, we need to divide the remaining laps by total laps, that is, 37 1/2 divide by 50 or 37.5 divided by 50 which will be equal to 0.74 or 3/4.

    37 1/2 / 50 = 0.74 or 3/4

    Hence, the right answer to the riddle is 3/4
    Did you answer this riddle correctly?
    YES  NO  

    McDonalds Riddle

    Hint: The key is to first determine how much each item is worth. The drink is clearly worth 10, and it's apparent from the second line that the burgers are worth five.
    Pictures of the fries are each worth two, but you have to keep in mind that each individual packet of fries is worth one when you get to the next line. That has baited people into thinking, incorrectly, that the last line is 5 + 2 x 10.

    The fourth line has also thrown many people off because it involves order of operations after already including the tricky single packet of fries.

    Multiplication comes before addition, so you have to multiply one packet of fries by one drink and then add that to one burger. Thus, 5 + (1x10) = 15.
    Did you answer this riddle correctly?
    YES  NO
