Answer 1

Method of Solution:


In this Question, There has given 3 Double Triangle.


Let's Solve First Queries!

In Triangle [1] , Considering on Triangles (First and second)

[Adding Both Triangle one by one and subtract them ]


First Triangle = 4+9+2 => 15

Second Triangle = 3+6+1 => 10

Hence, Difference between them = 15-10 => 5

---------------------------------------------------------------


Considering on Second Queries!


First Triangle = 7+3+1 => 11

Second Triangle = 8+6+5 => 19

Hence, Difference between them = 19-11=> 8

-------------------------------------------------------------


Considering on Third Queries

First Triangle = 6+1+2 => 09

Second Triangle = 9+4+7 => 20

Hence, Required Difference Between them = 20 - 09 => 11

Thus, Required Value is (11).


Therefore, Option C is the Correct Answer!
