Question

Only for genius -

Draw one line on this equation to make the above equation correct ⤴​

Answer 1

There are two ways to get to a conclusion .

Number 1 :-

Insert a dash over the equal to sign .

5 + 5 + 5 + 5 = 20

20 cannot be equal to 555 .

But if we put " not equal to sign " before 555 , then think about it ...

20 = 555 is a false statement .

20 ≠ 555 is a true statement .

Hence we can draw one line across the "equal to sign ".

5 + 5 + 5 + 5 ≠ 545

Number 2 :-

Insert a dash on any of the plus signs to make the number 5 + 5 as 545 .

This will be exactly equal to the value and LHS will be equal to RHS .

5 + 545 + 5 = 555

What ? O_o

We are drawing a line on the "+" sign to make it "4" .

This will make the number 545 .

545 + 5 + 5 = 555 is absolutely true .

Answer 2

$\textbf{\large{\underline{Answer :-}}}$

$\textbf{\underline{Logical Answer :}}$

The Given Equation =

$\tt{\implies5 + 5 + 5 + 5 = 555}$

To get the number given as the answer,

A slanted line (/) should be made on the first '+' sign.

By adding a line the '+' sign will look like 4.

So, by adding the slanted line , the new Equation =

$\tt{\implies545 + 5 + 5 = 555}$

$\tt{\implies545 + 10 = 555}$

$\tt{\implies555 = 555}$

$\therefore$LHS = RHS

$\therefore$ The answer :

To get the the answer as 555 from the given Equation, we need to add a slanted line (/) on the first '+' sign, to make it look like 4. Which will make the Equation correct by just adding one line.

$\textbf{\underline{Answer according to Maths :- }}$

As we all know, when a Equation is not correct and doesn't have it's both sides same, '≠' is used.

≠ sign means NOT EQUAL

Example :

4 + 1 ≠ 6 - 4

Now, as the question says =

$\tt{\rightarrow5 + 5 + 5 + 5 = 500}$

$\tt{\implies20 \: \not = \: 500 }$

The Equation doesn't have it's both sides equal. Therefore we can even use '≠' sign to make the equation correct.

$\tt{\implies5 + 5 + 5 + 5\not =500 }$

$\therefore$To make the Equation correct we have used only in line (/) on the equal sign.
