Very easy,

(1) (3⊕1)⊕2

(3⊕1) = 2.3 -1 = 5

=> 5⊕2 = 2.5- 2= 8

(2) 6⊕3 = 2.6 - 3= 9

(1)-(2) = 8 - 9 = -1

=> absolute value of -1 is 1.

Answer B.

a⊕b = 2a-b
(3⊕1) = 2(3)-1 = 6-1 = 5
5⊕2 = 2(5)-2 =10-2 = 8
6⊕3 = 2(6)-3 = 12-3 = 9

(3⊕1)⊕2 - 6⊕3 => |8-9| => |-1| => 1

IMO B

Given that a ⊕ b = 2a – b and we need to find the absolute value of the difference between (3 ⊕ 1) ⊕ 2 and 6 ⊕ 3

Lets start by finding the value of 3 ⊕ 1

To find 3 ⊕ 1 we need to compare what is before and after ⊕ in 3 ⊕ 1 and a ⊕ b

=> We need to substitute a with 3 and b with 1 in a ⊕ b to get the value of 3 ⊕ 1

=> 3 ⊕ 1 = 2*3 – 1 = 6 - 1 = 5

=> (3 ⊕ 1) ⊕ 2 = 5 ⊕ 2

Similarly, 5 ⊕ 2 = 2*5 - 2 = 10 - 2 = 8
=> (3 ⊕ 1) ⊕ 2 = 8

6 ⊕ 3 = 2*6 - 3 = 12 - 3 = 9

=> Absolute value of ((3 ⊕ 1) ⊕ 2) - 6 ⊕ 3 = | 8 - 9 | = |-1| = 1 (Watch this video to learn about the Basics of Absolute Value)

So, Answer will be B
Hope it helps!
