Question

if 6+ 4 = 210 then ? +? = 123 please solve this.. It's very important..

Answer 1

Given,

⇒ 6 + 4 = 210

We know that,

⇒ 6 + 4 = 10 and ( 6 - 4 = 2 ).

Here, we got that final number is formed by difference and sum of numbers and the sum is kept of right side while difference on just right to the sum.

Now,

⇒ ? + ? = 123

So, we have to find 2 numbers such that their difference is 1 and sum is 23.

Let the numbers are 'x' and 'y'.

Now,

 ⇒ x + y = 23  ----- ( 1 )

      " AND "

⇒ x - y = 1    ------- ( 2 ).

By adding ( 1 ) and ( 2 ),

⇒ x + y + x - y = 23 + 1

⇒ 2x = 24

⇒ x = 24 ÷ 2

 ∴ x = 12.

By substituting the value of ' x ' in ( 1 ),

⇒ x + y = 23

⇒12 + y = 23

⇒y = 23 - 12

∴ y = 11.

Again,

⇒ ? + ? = 123

∴ 12 + 11 = 123.
