Question

$32-[48÷\{36-(27-\overline{16-9})\left\}\right]=?$
(a) 29
(b) $\frac{520}{17}$
(c) none of these

Answer 1

(a) 29
Explanation:
Given expression:
= 32 $-$ [48 $÷$ {36 $-$ ( 27 $-$ $\overline{16-9}$)}]
= 32 $-$ [48 $÷$ {36 $-$ ( 27 $-$ 7)}] (Removing bar)
= 32 $-$ [48 $÷$ {36 $-$20}] (Removing parentheses)
= 32 $-$ [48 $÷$ 16] (Removing braces)
= 32 $-$ 3 (Removing square brackets)
= 29
