$18$ of $[59-7\times 8+(26-3of5)]$ is equal to

• A. $-188$
• B. $+144$
• C. $-144$
• D. none of these

Answer 1

The correct option is D none of these

$18of[59-7\times 8+(26-3of5\left)\right]$ $=18\times [59-7\times 8+(26-3\times 5\left)\right]$

$=18\times [59-56+(26-15\left)\right]$ [ First we are going to solve bracket ]

$=18\times [59-56+11]$

$=18\times [3+11]$

$=18\times 14$

$=252$
