Question

34:12:25:? solve it. ​

Answer 1

Givern:

We have terms are in proportion.

To Find:

We have to find 4th term?

Step-by-step explanation:

• Let the last term be x.

• We know in proportion product of extreme terms is equal to the product of mean terms.

• We have the proportion 34:12::25:x

             [tex]34\times x=12\times25\\ x=\frac{12\times25}{34} \\ x=\frac{150}{17} [/tex]

Hence, value of x is$\frac{150}{17}$.

Answer 2

Answer:

10  

Step-by-step explanation:

According to the information provided in the question it is given as

34:12:25:?

We need to solve the question means to find the next number

As per given in the question it is look like the ratio in which first set is having the both numbers but in second set only one number is given we can find the second number by simple cross multiplication as follows

First we have to identify the relation between 34 and 12

In 34 has two digits 3 and 4

By simple Multiplication of two digits we get get second

=3 x 4

= 12

number 12

In the same manner

In 25 ( digits are 2 and 5)

Multiplying these two digits

We get required  Next number

=2 × 5 = 10

Hence the next number is = 10

Hence series is like this

34:12:25:10
