Select the correct equation after interchanging operations ‘+’ and ‘-’ and numbers ‘4’ and ‘8’.

We check all option sequentially 

Check option (A) $$ 2+8-4= 9 $$

Interchange opration  + and - and numbers 4 and 8

$$ 2-4+8 = 9$$

From LHS $$ 2-4+8 $$

$$\Rightarrow 10- 4 $$

$$\Rightarrow 6 $$  its not staisfied.

check option (B) $$8+4-2=10$$

Interchange opration + and - and numbers 4 and 8 

LHS $$ 4-8+2 $$ 

$$\Rightarrow 6-8$$

$$\Rightarrow -2 $$ its not staisfied .

check option (C) $$4-8+11 =1 $$

Interchange opration + and - and numbers 4 and 8

From LHS $$ 8+4-11 $$

$$\Rightarrow 12-11 $$

$$\Rightarrow 1 $$ RHS its staisfied .

therefore (C) is staisfied Ans
