Question

120 : 180 : : 200 : ?​

Answer 1

Answer:

Let the unknow number be x

so, 120 : 180 : : 200 : x

Now, we already know that product of means : : product of extremes

So,

product of means = product of extremes

⇒ 180 * 200 = 120 * x

⇒ 36,000 = 120x

⇒ 36,000/120 = x

⇒ 300 = x

So, 120 : 180 : : 200 : 300

∴ 120 : 180 : : 200 : 300
