Answer 2

45 is your answer

Given

→ 1 + 4 = 5

→ 2 + 5 = 12

→ 3 + 6 = 21

→ 5 + 8 = ?

To Find

Value of " ? "

Logic Used

Observe the puzzle carefully .

It is in the form of ,

→ x + y = x + xy

Observation skills are needed to solve this type of questions easily

Solution

Let's take 1st one ,

→ 1 + 4 = 5

Here , x = 1 & y = 4

So , xy = 4

⇒ x + xy = 1 + 4 = 5

So , 1 + 4 = 5

→ 2 + 5 = 12

Here , x = 2 and y =5

So , xy = 10

⇒ x + xy = 2 + 10 = 12

So , 2 + 5 = 12

→ 3 + 6 = 21

Here , x = 3 and y = 6

So , xy = 18

⇒ x + xy = 3 + 18 = 21

So , 3 + 6 = 21

Like these ,

Take 5 + 8 = ?

Here , x = 5 and y = 8

So , xy = 40

⇒ x + xy = 5 + 40  = 45

So ,

5 + 8 = 45
