Question

Hey, please insert the missing character!​

Answer 1

Answer:

20

Step-by-step explanation:

Here we consider sum of first three numbers of the columns and divide the sum by the last number of a column.

For example, in the first column 6+7+8 = 21

Here the last number of this column is 3

Hence, 321=7

Hence, in every column if we apply the same condition it is all equal to 7

Let us consider second column

Here we have 7+15+13 =35.

In this column last digit is 5.

Hence, we have 535=7

Let us apply the same for third column 

74+25+?=7⇒?=49−29=20
