Solution

The correct option is A
True

$\frac{5}{3 x}$ = $\frac{25}{27}$

By cross multiplication, we get

$5 \times 27 = 3 x \times 25$

$\Rightarrow 3 x = \frac{5 \times 27}{25}$

$\Rightarrow x = \frac{5 \times 27}{3 \times 25}$

$\Rightarrow x = \frac{9}{5}$

$= 1.8$ , which lies between 1 and 2.
