Suppose if we add 9 & 5 and get 2 as the answer then how is it possible? This tricky math problem pushes the reader to think outside the box and lookout for possibilities where certain non obvious problems also have obvious solution. Try this problem before you check the answer.
Answer : This math problem demands a little bit of logic from your side. Knowing that adding 5 to 9 can never give 2 as the result, one must quickly come to the conclusion that the question wants you to deviate a little from the mathematical approach and find out some instances when this could be possible. One such instance is in the case of a clock where normal addition of numbers is interpreted in a different manner. If you look closely, adding 5hrs to 9AM will result into 2PM. That was pretty simple. Isn’t it?
Did you give the right answer? Let’s dive into some other tricky math problems to test your logical capability.
A Logical Equation
Question : Consider the following equations :
2 + 3 = 11 ...(I) 4 + 6 = 34 ...(II)
If the above two equations are true, then 3 + 5 = ?
Answer : This question is a bit similar to the first problem. It demands more of a logical reasoning rather than mathematical reasoning. No doubt 2 + 3 can never be equal to 11 nor 4 + 6 can be equal to 34. To solve such kinds of problem, try to find a common pattern between two equations that led to produce the result. The pattern observed here is :
- Multiply the two numbers on LHS and
- Add the product to the sum of the two numbers
In this case, for 2 + 3 :
(2x3) + (2+3) = 11
And for 4 + 6 :
(4x6) + (4+6) = 34
Hence if we proceed by the same logic to find out the value of 3 + 5, we will get :
(3x5) + (3+5) = 23
Hence 23 is the answer.
Let’s see one more question.
Fill in the blanks
Question : Fill in the blanks with proper mathematical operators to make the following equation true :
36 __ 13 __ 4 __ 2 = 10
Answer : The problem requires you to play the trial and error and come up with the right answer. The right answer is :
36 - 13 x 4 / 2 = 10
Got it? Wait! The main problem is not about finding the right operators, it’s about proper evaluation of the expression :
36 - 13 x 4 / 2
You must have a crystal clear concept about ORDER OF OPERATIONS to evaluate this expression otherwise you will have a hard time getting the answer. As I have already discussed in my article here, multiplication and division have same preference and if they both occur in an expression they must be evaluated left to right. Thus in the above expression we will perform the multiplication first :
36 - (13 x 4) / 2 = 36 - 52 / 2
Now we will evaluate the division :
36 - 52 / 2 = 36 - 26 = 10
