The value of
$28 ÷ [25 + 8 ÷4 - \begin{Bmatrix}25 + (25 \, of \, 8 ÷ 20) - (125 ÷ 5\, of \,25 ) \end{Bmatrix}] + ( 25 × 5)$ is :
Answer & explanation
Correct answer: option 4
$28 ÷ [25 + 8 ÷4 - \begin{Bmatrix}25 + (25 \, of \, 8 ÷ 20) - (125 ÷ 5\, of \,25 ) \end{Bmatrix}] + ( 25 × 5)$
28 ÷ [25 + 2 - {(25 + 10) - 1}] + 125
= 28 ÷ [27 - 34] + 125
= \(\frac{28}{-7}\)+ 125
= -4 + 125
= 121
