Question 41

Select the option that can replace the question mark (?) in the following equation.

$$ 2 + 5\div [5+8\div( 1+\frac{1}{3}) - 1] $$ = ?

Solution

= $$ 2 + 5\div [5+8\div( 1+\frac{1}{3}) - 1] $$

= $$ 2 + 5\div [5+8\div( \frac{4}{3}) - 1] $$

= $$ 2 + 5\div [5+8 \times \frac{3}{4} - 1] $$

= $$ 2 + 5\div 10 $$

= $$ \frac{5}{2} $$

Hence, option B is the correct answer.
