Question

12:3::34:? solve it number analogy​

Answer 1

Answer:

8.5

Step-by-step explanation:

First consider that 12:3=34:x

then 12/3=34/x

= 4=34/x

= x=34/4

= x=8.5 or 85/10

Answer 2

The answer is 8.5.

Step-by-step explanation:

It is simple analogy problem.

12:3::34:?

WAY 1:

If we see the first two numbers, 12 and 3, we can find that 12 divided by 4 is 3.

Similar division can be done with 34 also.

So, 34 divided by 4 is 8.5.

Hence, 12:3::34:8.5.

WAY 2:

This can also, be done by cross multiplication.

Let the unknown number be x.

Then $\frac{12}{3} = \frac{34}{x}$

$x = \frac{34\times 3}{12}$ = 8.5
