22. SSC CHSL 27th May Shift 1 - QA | Simple Equation - SSC

9 ÷ [5 + 7 ÷ {9 + 9 ÷ (9 + 9 ÷ 4)}] = ?

A.
$\frac{48}{40}$
B.
$\frac{63}{40}$
C.
$\frac{59}{40}$
D.
$\frac{37}{40}$

Answer: Option B

Explanation :

Given: 9 ÷ [5 + 7 ÷ {9 + 9 ÷ (9 + 9 ÷ 4)}]

= $\frac{9}{5 + \frac{7}{9 + \frac{9}{9 + \frac{9}{4}}}}$

= $\frac{9}{5 + \frac{7}{9 + \frac{36}{45}}}$ = $\frac{9}{5 + \frac{7}{9 + \frac{4}{5}}}$

= $\frac{9}{5 + \frac{35}{49}}$ = $\frac{9}{5 + \frac{5}{7}}$

= $\frac{63}{40}$

Hence, option (b).
