Question

31:8::43 next number series​

Answer 1

Answer:

The correct answer is 11.1

Step-by-step explanation:

We know that,

product of means = products of extremes

thus, a:b :: c:d ⇔ (b*c) = (a*d)

Let, the next number = x

so, 31:8 :: 43:x

⇒ (x * 31) = (8 * 43)

⇒ x = (8 * 43)/31

⇒ x = 344 / 31

⇒ x = 11.1

next number = 11.1
