<h2>The value of x = 36</h2>
Step-by-step explanation:
We have,
x, 45, 40 and 50 are in a proportion.
x : 45 : : 40 : 50
To find, the value of x = ?
We know that,
a : b : : c : d
Product of means = Product of extremes
a × d = b × c
∴ a × d = x × 50
Also,
b × c = 45 × 40
∴ x × 50 = 45 × 40
⇒ x =
⇒ x =
⇒ x = 9 × 4 = 36
∴ The value of x = 36
