In each of these questions an equation is given with a questions mark (?) in place of the correct figure on the right hand side which satisfies the equality. Based on the values on the left hand side and the symbol of equality given, you have to decide which of the following figures will satisfy the equality and thus come in place of the question mark.
Symbol Stands for
> Greater than
= Equal to
< Lesser than
≥ Either greater than or equal to
≤ Either Lesser than or equal to

$$-[(\sqrt { 676 } -\sqrt { 196 } )\times (-1.7)]=?$$
