Question 30

In the following question, select the number which can be placed at the sign of question mark (?) from the given alternatives.

Solution

In each column, the first three numbers will be added and divided by 2 for obtaining the fourth number.

6+9+11 = 26 ==> $$\frac{26}{2}$$ = 13

7+11+2 = 20 ==> $$\frac{20}{2}$$ = 10

12+4+6 = 22 ==> $$\frac{22}{2}$$ = 11

Hence 11 will come in place of question mark.
