Question

Help me pls guys fast pls

Answer 1

We have to find, the value of missing number(?).

Solution:

The pattern follow:

Inner number = Square of upper number - (Sum of below number)

In figure 1,

44 = 7 × 7 - (2 + 3)

     = 49 - 5 = 44

In figure 2,

71 = 9 × 9 - (7 + 3)

     = 81 - 10 = 71

Similarly:

In figure 3,

? = 5 × 5 - (1 + 2)

⇒ ? = 25 - 3

⇒ ? = 22

∴ Missing number (?) = 22

Answer 2

Given :  Three triangles  , number on the vertex ad inside the triangle

To Find : Missing number inside last triangle

Solution:

           7                                

         44                                  

 2                 3

   

7² - (2 + 3)

= 49 - 5

= 44

           9                                

         71                                  

 7                 3

   

9² - (7 + 3)

= 81 - 10

= 71

           5                                

         ?                                  

 1                2

   

5² - (1 + 2)

=25- 3

= 22

Hence 22  will comes inside last triangle

Logic  :  Square of tope vertex number - ( sum of numbers at base)  = number inside triangle
