In the following equation, two signs and two numbers need to be interchanged to make it correct. Select the appropriate signs and numbers from the given alternatives.
$$6 \times 8 + 2 = 20$$
Given expression  $$6 \times 8 + 2 = 20$$Â
we check (A), (B), (C), it is not staisfied that LHS = RHSÂ
then we check option (D) $$ + and \times $$, 6 and 8
we Interchange two Signs and two numbers in the given expression
$$ 8 + 6 \times 2 = 20$$
From LHS $$ 8 + 6 \times 2 $$
$$ \Rightarrow 8 + 12 $$
$$ \Rightarrow 20 $$ RHSÂ
that means its is staisfied .
therefore (D) AnsÂ
