x × 18 = 16× 72

18x = 1152

x = 1152/18

x = 64

To FiNd :-

→ Value of x

FoRmUlA uSeD :-

→Product of Mean = Product of Extreme

SoLuTiOn :-

According to Question,

$\rightarrow \frac{16}{x} = \frac{18}{72}$

By Cross – Multiplication,

$\rightarrow 16 \times 72 = x \times 18$

$\rightarrow \frac{16 \times 72}{18} = x$

Exchanging LHS and RHS,

$\rightarrow x = \frac{16 \times 72}{18}$

$\rightarrow x = \frac{16 \times \cancel{72}}{ \cancel{18}}$

$\rightarrow x = 16 \times 4$
