3 - [1.6 - {3.2 - (3.2 + 2.25 + x)}] = 0.65. The value of x is :


A) 0.3

B) 0.7

C) 3

D) 7

Answer:

Option C

Explanation:

Given $3-[1.6-{3.2-(3.2+\frac{2.25}{x})}]=0.65$
$3-[1.6-{3.2-3.2+\frac{2.25}{x}}]=0.65$
$3-[1.6+\frac{2.25}{x}]=0.65$
$3-1.6-\frac{2.25}{x}=0.65$
$\frac{2.25}{x}=1.4-0.65$
$\frac{2.25}{x}=0.75$
$x=\frac{2.25}{0.75}=3$
