240 x 25 =6000 and 80 x 75 = 6000

so, they arein proportion

Answer 2

25, 75, 80, 240 are in proportion.

Step-by-step explanation:

We have,

25 : 75 : : 80 : 240

To find, 25, 75, 80and 240 are in proportion or not.

∴ 25 : 75 : : 80 : 240

Here, a = 24, b = 75, c = 80 and d = 240

We know that,

Product of means = Product of extremes

⇒ b × c = a × d

∴ b × c = 75 × 80 = 6000 and

a × d = 25 × 240 = 6000

∴ Product of means = Product of extremes = 240

Thus, 25, 75, 80, 240 are in proportion.
